Out of This World

flying saucerMake a flying saucer and watch it whiz down a zip line! This project is the perfect blend of simplicity, creativity, and action. We even have a saucer flight video for you!

We read Space Case, written by Edward Marshall, and illustrated by James Marshall (Puffin Books; reprint edition, 1992). When a bright yellow saucer-shaped thing arrives from outer space, it doesn’t find the natives (a cow, a chicken, and a jack-o-lantern) to be very forthcoming in conversation. But then it encounters three trick-or-treaters, who mistake him for a new kid in the neighborhood. The quartet have a wonderful time trick-or-treating until Buddy McGee realizes that the thing isn’t wearing a costume. He invites it home, and even takes it to school the next day. But when the thing learns there will be no trick-or-treating that night, it prepares to depart. It promises, however, to return for Christmas!

You’ll need:

  • 2 sturdy paper plates
  • 1 strip of poster board (approximately 1.5″ x 22″)
  • A selection of dot stickers
  • 2 toilet paper tubes
  • 3 rectangles of grey construction paper (approximately 2″ x 6″ each)
  • 1 jumbo pom-pom (mine was 1.75″)
  • 1 large wiggle eye
  • 1 clear plastic drinking cup (I used a 2.75″ tall hard plastic cocktail glass)
  • 1 jumbo paper clip (mine was 1.75″ long)
  • Flying saucer decorating materials (more on this below)
  • 6 squares of yellow and/or red cellophane (approximately 5″ x 5″)
  • A length of 24-gauge wire
  • Scissors, stapler and tape for construction
  • Markers for decorating
  • Hot glue

finished saucerFirst, decorate a strip of poster board with dot stickers “lights” (we used silver metallic poster board and yellow dot stickers, but any color combination will do). Circle the poster board strip around the bottom of a paper plate and staple (or tape) the circle closed. In the demonstration photo below, I used purple poster board so it would stand out against the white plate. For the actual project, the poster board was silver with white backing.

We offered tin foil, embossed foil paper, sparkle stems, dot stickers, and some foil confetti stars I picked up in the party section of Michaels craft store. Try to keep the art materials nice and light so they don’t weight the saucer down too much. Also, don’t let kids attach anything to the paper clip hook. Otherwise, the saucer’s flight down the wire might be hampered.

When you’re finished decorating, stack 2 squares of cellophane on top of one another (we used red and yellow). Pinch the middle of the cellophane squares together, twist them tightly, and secure with tape. Repeat the above steps twice more. You now have 3 “flames” for your saucer’s rocket boosters.

crafting wire

Katie and I stretched 25 feet of wire between the launch site and the landing pad. I handled the launches, Katie handled the landings. To help my grip on the wire, I wrapped my end of the wire around a wooden dowel. I slipped the saucer’s paper clip hook onto the wire, lifted my end of the wire to give the saucer a sliding start, and watched it fly!

Important: Katie and I tested the wire the day before the program. When we were finished, we lightly coiled it and set it on a table. Unfortunately, that was enough to cause the wire to kink. The next day, the first saucer on the wire got snagged on the kinks. We had to quickly unspool a fresh length of wire. After that, it was smooth sailing.

If you’re going to do this project with a crowd of kids, I suggest doing some prep ahead of time. Definitely prep the upper and lower halves of the saucers  (i.e. hot glue the poster board circle to one paper plate, and the 3 tube boosters to the other plate). While the kids were decorating the top half with markers, we used a number system (similar to the ones used in delis and bakeries – we also used it on this project) to call them to the hot glue stations to get the bottom half of their saucer’s attached. Then they wrapped the boosters with grey construction paper, attached the cup, and proceeded to decorating.

Also, in our version of this activity, the kids brought their alien-free saucers to the launching site. I loaded an alien in it, taped the cup down, and then sent the saucer zooming down the zip line. If you decide to do this, make sure the kids attach the cup with just 1 piece of tape. This will allow you to easily lift the cup and place the alien on the saucer. But don’t forget to tape the lid down tightly after that!

Katie also prepped the cellophane flames in advance so there would be plenty of time to fly the saucers. Kids could take as many flights as they wanted.

It was…wait for it…a total blast!

Flannel of the Future

flannel board 2015Some of you may recall this post, in which I visited my friends at scienceSeeds and reported on all the cool science toys they are currently playing with. There was one toy, however, that I didn’t include because I wanted to do a special post on it later.

The time has come for that post.

Get ready to usher your story time flannel board into 2015…may I introduce…the brilliant…the amazing…the mesmerizing…conductive thread! Yes, this thread conducts electricity, which means that your flannel can be rigged with lights!

You’ll need:

  • 1-2 pieces of felt (i.e. flannel)
  • 1 sewing needle
  • A length of conductive thread
  • 1 coin cell battery holder
  • LEDs (3mm or 5mm size are recommended)
  • 1 coin cell battery
  • Scissors
  • Hot glue (optional)

The good news is that all the electrical components listed above will cost you less than $10. A 30 foot bobbin of the thread is $2.95, and the LEDs are between 20¢-50¢ each. A battery holder is about $1.95, and the coin cell batteries, which can be purchased just about any retail store, are between $1-3 dollars (the one you see in the image below is size CR 2032). scienceSeeds buys most of their supplies from SparkFun Electronics, an online company.

electrical suppliesSince we were using lots of LEDs, Lindsay, our scienceSeeds flannel artist, decided to do 2 layers of flannel. The black “background” layer held the thread and the batteries, and a colorful top layer hid the stitching. The results were colorful, tidy, and sturdy. Here’s what the back of our flannel numbers looks like:

rigged upFirst, use the conductive thread to sew a coin cell battery holder to a piece of felt. It’s important that the battery holder is tightly connected to the felt. Lindsay recommends hot gluing the battery holder to the felt first, and then stitching the holder’s connections to the felt with the thread.

Next, push the legs of an LED through the felt. Curl the legs into circles using a small pair of scissors, jewelry pliers, or needle nose pliers.Then stitch the legs to the felt with the thread.

curled leg and threadBecause you’re making a circuit, it’s essential to connect negative to negative and positive to positive. Therefore, the same thread that is connected to the negative post of the battery holder needs to be connected to the negative LED leg. Likewise, the same thread that is connected to the positive post of the battery holder needs to be connected to the positive LED leg.

Worried you won’t be able to rig things up correctly? Worry no more. The battery holder’s negative post is clearly marked, and the negative leg of an LED is always the shorter of the two.

led leg and holderYou can just connect one LED, or you connect a train of them. One important thing to note: if you’re using just one LED, the battery tends to heat up (as opposed to multiple LEDs in a strand, which share the power load). If you’re using just one LED, you might consider adding a resistor (i.e. an electrical component that limits the flow of a current through a circuit). Many LEDs already come with resistors.

When everything is connected, slip a coin cell battery into the battery holder. Your LEDs will activate, and your flannel board will glow! We discovered that the weight of our LEDs, battery holders, and coin batteries made our flannel numbers drop off the flannel board (Viva Las Vegas!). But the problem was quickly solved with a bit of Velcro.

Many thanks to scienceSeeds for rigging up the fantastic 2015 flannel!

Robots at the Ready

robots at the readyA robot backpack? Yes indeed! Now you and your robot pal can embark on a series of terrific adventures. But the best thing about this story time? The author, Jared Aldwin Crooks, came to read the book to us!

jared aldwin crooksIn addition to penning a children’s book, Jared studied astrophysics, has worked at NASA, and is currently obtaining Masters degrees in International Policy and Mechanical/ Aerospace Engineering here at Princeton University. There’s a short interview with him at the end of this post!We read The Several Strange Adventures of Max and Ding, written by Jared Aldwin Crooks and illustrated by Scott T. Baldwin (Crooks with Books, 2014). Maximilian Finch (Max for short) lives in a sleepy town where not much happens. During school breaks his classmates go to all sorts of exciting places, but not Max. But one Sunday, Max builds a robot named Ding. That week, Max and Ding hit the road – riding paper planes through jungles, climbing mountains, visiting the circus, digging to Atlantis, fishing for treasure, building a bridge to the moon, and discovering new planets. Thanks to his pal Ding, Max now has plenty to talk about!

You’ll need:

  • 1 box for robot body (mine was 4 ½” X 4 ½” x 6” – a small tissue box works too)
  • 1 smaller box for robot head (mine was 2.5″ x 3.25″ x 4″)
  • 1 box cutter
  • 1 small craft stick
  • 2 strips of white poster board for backpack straps (approximately 1″ x 28″)
  • A 20″ piece of mesh tubing (string, ribbon, or yarn works too)
  • 2 rectangles of poster board for arms (approximately 1.5″ x 5.75″)
  • 2 rectangles of poster board for legs (approximately 1.5″ x 11″)
  • Robot decorating materials (we used metallic duct tape, prism tape, tin foil, beverage lids, washed Altoids tins, twisteez wire, sparkle stems, paper cups (in silver and gold), small plastic cups, embossed foil seals, craft ties, dot stickers, rectangular stickers, foil star stickers, color masking tape, balloon stick cups, grey construction paper, embossed foil paper, and mylar).
  • Scissors, tape, and glue stick for construction
  • Markers for decorating
  • Hot glue

To make a robot backpack, cut four, 1.5″ slits in a box. Then, use a small craft stick to enlarge the slits a little (this will make it easier to slide the backpack straps through the slits later).

backpack box slitsSlide the white poster board straps through the slits like so:

backpack strapsNow, holding the box firmly to your back, curl the straps over your shoulders, adjust them, and staple them. Put pieces of masking tape over the staples (thus avoiding staple scratches or clothing snags). Later, when your robot is finished, you’ll want to tie a piece of mesh tubing (or string, ribbon, or yarn) around both straps to keep them from sliding off your shoulders.

strap stepsWhen the backpack straps are finished, you’ll need to hot glue the head, arms, and legs on your robot’s body. You can do that now, or wait until you’ve decorated your robot a little. I offered OCuSoft lid scrub boxes as an option for the robot’s head. As you can see, when covered with tin foil, they look like fantastic smiling robot faces!

ocusoft box headAnother great recyclable discovery? balloon stick cups make great robot antennae holders. I definitely use balloon sticks for projects (see here, here, and here) but I don’t use the cups as much. But a doubled-up sparkle stem fit perfectly in the narrow end of the cup.

robot antennaeFor decorating, we offered metallic duct tape, prism tape, tin foil, beverage lids, washed Altoids tins, twisteez wire, sparkle stems, mesh tubing, paper cups (in silver and gold), small plastic cups, embossed foil seals, craft ties, dot stickers, rectangular stickers, foil star stickers, color masking tape, balloon stick cups, grey construction paper, embossed foil paper, and mylar.

Here’s Jared, his robot, and our program area after our creative little endeavor concluded!

jared and robotHi Jared! Tell us a little about yourself!
Hey there! My name is Jared Aldwin Crooks. I grew up in Fort Worth, Texas before coming to Princeton to get my undergraduate degree in Astrophysics and my Masters degrees in International Policy and Mechanical/ Aerospace Engineering. I have always loved creating things, whether it is some kind of contraption, food, or just writing down all of the things that are in my head. My creative partner, Scott T. Baldwin, and I are always working on a new project or book!

My passion is making the world around me a better place and I believe this can be done through little improvements over time (kaizen). My wife and I started NouriBar, a social venture that makes all-natural fruit and nut bars and for every bar purchased we work with the local communities to feed a child in need a hot meal in school. I also love doing radio and voice work. During my time at NASA, I was one of the narrators for the ScienceCasts! I love to cook and watch great films (Kurosawa, Bergman, Hitchcock).

What were some of your favorite books when you were a kid?
I was constantly reading as a kid. One of my all-time favorite books growing up was a picture book called Corduroy. The artwork seemed to jump out at you on each page and I loved the storyline! Other books that I really loved include any and all of the books from The Little Golden Books series, the Chronicles of Narnia series by C.S. Lewis, The Little Engine that Could by Watty Piper, and the Little House on the Prairie series by Laura Ingalls Wilder.

Why did you decide to write this book?
This book is loosely based on the daydreams that I had growing up. I had always wanted to share the things that had captured my imagination growing up; the stars, building things, wildlife, robotics etc. I also wanted write something to inspire kids to dream big and especially wanted to make sure that young kids of color could see another kid building and imagining things that are not typically represented in stories that are accessible to them. I linked up with my wonderful creative partner, Scott T. Baldwin right at the beginning and he shared the same vision that I had and he illustrated each page to show exactly what we had dreamed; so this is how the book came about!

What was an unexpected difficulty in writing this book?
One surprising difficulty I experienced while writing this book was trying to fit all of Max and Ding’s activities into 7 days! They have so many places to choose from and travel!

If Ding the robot appeared right now, where would you go?
Ding and I would most definitely travel to Cape Town, South Africa and have a swimming contest with a few great white sharks before hopping over to New Zealand and going to all of the Lord of the Rings filming locations!


Many thanks to Jared Aldwin Crooks for sharing his book and being our special guest!
