Red Letter Day

red letter day

Hosting a community event table and need something creative, literary, and simple? We highly recommend this wooden letter key chain project, which clips oh-so-conveniently to your bag or backpack!

The project just requires wooden letters, markers, rubber bands, and carabiners. We bought our carabiners from Oriental Trading Company – a bag of 50 costs $12. Our 2″ wooden letters are from Amazon. A set of 120 pieces (which also included symbols # & @ $) cost $22. And they come in this handy-dandy tray too!

O Frabjous Day

go ask aliceThis year marks the 150th anniversary of the publication of Alice in Wonderland, and we decided to honor the occasion at Princeton University’s Community & Staff Day! Our event table was stocked with some super, yet simple-to-assemble, thaumatropes. There was also some breakdancing. Well, sort of. Scroll to the bottom of the post to see our mashup of Alice and the 1980s.

A thaumatrope is a Victorian optical toy. It consists of two images printed on opposite sides of a paper disc or card. When you twirl the thaumatrope, its two pictures appear to blend into one. Most thaumatropes are twirled using string. We decided to mount ours on pencils.

thaumatrope demoYou’ll need:

  • 1 Alice thaumatrope template, printed on 8.5″ x 11″ white card stock
  • 1 pencil (I ordered terrific ones from Oriental Trading Company)
  • Scissors and tape for construction
  • Colored pencils (or crayons) for decorating

We offered 4 Alice-themed templates, drawn by our amazing student artist, Aliisa Lee.

thaumatropesFirst, select a template, and use colored pencils or crayons to color it. Then, fold the template in half (along its faint grey line).

folded thaumatropeFlip the thaumatrope over, and tape a pencil to the back of one of the panels like so:

thaumatrope step 2Fold the thaumatrope closed, then secure the panels together with a piece of tape. You’ll also want to tape both sides of the thaumatrope to the pencil, to make it extra sturdy.

thaumatrope step 3Hold the pencil between your palms and roll it briskly back and forth. Your thaumatrope will turn, and the two images will appear as one!

twirlingHere’s what our craft table looked like (and, if you’d like to explain a bit of the science behind how the device works, here’s a pdf of our thaumatrope table sign):

thaumatrope work tableWe also had some pens and blank thaumatrope cards on hand, just in case kids wanted to try their hands at making one from scratch.

optical illusion tableWhile color print-outs of optical illusions work just fine, I highly recommend this pack of Usborne optical illusion cards. There are 50 illusions in the pack. They’re colorful, sturdy, and the science behind the illusions is explained on the back of the cards. The deck retails for $10.

optical illusion cardsNo event is complete without a little costuming, and Marissa and I raided both our closets and the Costume Shop at the Lewis Center for the Arts for our garb. This was completely unintentional when we snapped the shot, but…don’t Marissa and I look like we’re going to bust out some 80s breakdancing moves?

break danceMaybe it’s the shoes? The jaunty pose? Hmmmm. What if we adjust the backdrop a little…

welcome to the 80sOh yeah. I dare you to pin it.


Many thanks to the Costume Shop at the Lewis Center for the Arts for the costume loans, and to Aliisa Lee for triggering some totally radical 80s flashbacks.

Quill Pens

quill pensNeed a simple project for a big event? Perhaps these quill pens will do the trick!

Last Saturday, Cotsen hosted a table at Princeton University’s Community & Staff Day event. Because of the big crowds, we needed something simple, fun, fast, and literary. Last year, we made flying books. This year, we decided to make Harry Potter-esque quill pens.

We were, of course, dressed in hats and robes. Even though it was 85 degrees out. Because comfort never comes before costuming, am I right?

wizard robesYou’ll need:

First, twist a sparkle stem into the desired shape. We offered 3 different shapes to choose from (even though some kids made their own shapes of course):

stemsPlace the sparkle stem on top of the feather. Then use masking tape to attach the feather and the sparkle stem to the the top of the pen. You can continue covering the pen with tape if you’d like (just make sure you don’t accidentally tape the cap on). Done!

pen from sideBelow you can see the layout of our event table, including a display pen floating in the upper right-hand corner of the photo. It’s always a good idea to have an example of the project displayed somewhere. That way, kids can see what to expect and grown ups can get a jump on gathering the appropriate supplies.

table side 1On the opposite side of our event tent was a mirror activity. Here, kids could use their newly-created quill pens to do some inverted writing and try their skills at mirror mazes.

table side 2The mirror activity is very simple to put together. We duct-taped 6 bookends to the back of an inexpensive door mirror and stood it up on the table.

mirrorSince we weren’t able to staff the mirror activities during the event, we printed up some display instructions (here are my mirror writing instructions). I put the instructions in a double-sided plastic display stand.

instructionsWe stacked practice paper and 4 types of mazes (which we found using Google images) on either side of the mirror. The mazes were really popular, even with older kids!

boys writingAt neighboring table, the Princeton Plasma Physics Lab brought all sorts of science toys for the crowds to play with. Including this Van de Graaff generator…
