Undersea adventure abounds as you cruise the sea in your sub! The sub also doubles as a spyglass, so you can spot all sorts of aquatic wildlife. See the happy jumping fish?
We recommend Rub-a-Dub Sub, written by Linda Ashman, and illustrated by Jeff Mack (Harcourt, 2003). Zooming around in an orange submarine, a little boy encounters numerous ocean creatures – a seal, a manta ray, a horseshoe crab, and an eel to name a few! But an encounter with an enormous shark forces him to quickly retrace his steps to the surface, where he finds himself safe and sound – in his very own bathtub.
You’ll need:
- 2 paper cups
- A box cutter
- Construction paper
- Scissors and tape for construction
- Markers for decorating
Optional:
- 1 paper towel tube
- Hot glue
I’ll show you the simplest version of the sub project first, then follow it with the paper towel tube variation. Use a box cutter to cut the circles in the bottoms of 2 paper cups. Make sure to leave a little ledge around the bottom of the cup.
Next, turn the cups end-to-end and connect them together with hot glue. If you can’t do hot glue, simply connect the cups with tape. We used black masking tape for the photo below, but regular tape works just as well.
For the paper towel tube version of the project, cut the holes in the bottoms of the cups. Then place a piece of paper towel tube inside the bottom cup (our tube piece was 6.75″ long but you might have to adjust yours a little). Place the second cup over top of the first…
Then hot glue (or tape) the two cups together. So…is the extra effort for the paper towel version worth it? You decide! Here’s a side-by-side comparison of the 2 projects. One could argue that the paper towel tube version looks more like a spyglass, but the cups-only version is cute too.
Next, cut a periscope shape out of construction paper, tab the bottom, and attach the periscope to the top of the sub. Finally, use markers to give your sub portholes, plates, rivets, and bolts. Any markers will do, but we really liked how silver metallic marker looked on the black paper cups.
Miss Marissa designed this awesome project, and she made a fantastic I-Spy game to go with it! To play, print up the characters in this template (click here for small on a single page, click here for large on multiple pages). Tape the characters in different locations and have the kids find them with their sub spyglasses. However, if you spot the shark you have to immediately head back to “home base.” This is especially funny if the shark is taped to the back of an adult who is wandering among the submarine searchers!
Calling all demigods and satyrs…with the simple command of “Maia!” your sneakers will sprout wings and fly! This project looks awesome and is super easy to put together. However, please note that winged sneakers are not recommended for use in or around Tartarus.
Next, take a small paperclip and bend the shorter loop backwards. Wrap the shorter loop with masking tape.
Use a glue dot or hot glue to attach the paper clip to the back of the felt wing.
Repeat the above steps with 3 more wings, then slide the wings onto your sneakers! Feel free to experiment with different colors too. Here’s a nod to one of my favorite Percy Jackson characters, Blackjack.
Interested in a cheaper, simpler version of this project? We did a whole post on how we 
Solve the riddles, find 3 keys, and discover an ancient temple at 
The 3 box locations were quite some distance apart on Princeton University’s campus, so there was a fair amount of excited running. Marissa went with the gang, and managed to get some great action shots.
Here’s my favorite. Look at those feet coming completely off the ground!
I don’t know about you, but I find rhyming clues really challenging to write. Especially when you want the kids to figure out where to go without being too obvious or clunky. I was, however, pretty happy with this one. Here’s a photo of the location:
And here’s the clue that led to it:
Here’s a shot from the side so you can get an idea of the size and how we constructed it.
The ramp in the front of the temple lifted to reveal a felt-covered doorway. From there, kids entered a creepy, cob-web covered chamber illuminated with votive LED candles. One at a time, the kids crawled across a floor rigged with bubble wrap to snag a golden treasure box (which we lit from above with an LED light mounted in the top of the treasure vault box).
The minute the treasure left the vault, it triggered cardboard spikes dropping from the ceiling! That was me outside the box, manually raising and lowering the spikes from a slit in the ceiling. There was lots of laughing and screaming. Good times!
The characters in the book have a couple run-ins with caiman, so the final touch was an alligator puppet (operated by Marissa) that snapped at the kids as they exited the temple. The hard-earned treasure boxes were plastic jewelry boxes I found at the Dollar Store. They were loaded with plastic gemstones as well. Each kid received a treasure box, and, to make reloading the treasure vault easier, we cut a little trap door in the back of the box.
After everyone had received a treasure box, we opened the temple back up and just let the kids have fun entering and exiting, dodging the spikes. Some of the younger siblings tried too (sans spikes of course). And then there was this little baby who was totally fascinated by the interior of the temple. She hung out for quite a while!
Addison Cooke and the Treasure of the Incas is a fantastic read-aloud. It’s hilarious, adventurous, faced-paced, with strong strains of Indiana Jones and The Goonies. Definitely looking forward to reading more books in this series!
