Who says a snail can’t be speedy? Start your engines, we’re putting it in 5th gear with a remote control snail racer rally!
We read Snail Crossing by Corey R. Tabor (Balzer + Bray, 2020). When Snail spots a delicious cabbage field across the road, he decides to motor over. However, many obstacles (birds, cars, rain, his own sense of direction) deter him from his goal. Thankfully, with the help of some new friends, it’s cabbage soup and tea for all! This book is hilarious and SO much fun to read aloud. Lots of laughter at story time! Highly recommend!
You’ll need:
- 1 box (ours was 4” x 4” x 4”, but a small tissue box works too)
- Poster board
- 1 wheel assembly (more on that below)
- 1 RC car or pull string
- Scissors, tape and/or glue for construction
- Markers for decorating
The snail part of this project is very simple. Decorate 2 poster board snail shells and attach them to both sides of a small box. To make the snail’s head and neck, round one end of an 8″ strip of poster board, then fold to create a head. Don’t forget the eye stalks! We also added a paper racing helmet, but that is optional. Tab the other end of the strip and attach it to the underside of the box.
If you are going to eventually make this a pull string snail like we did, you will find the wheel assembly instructions here. Finish the whole look off with color masking tape stripes and star stickers, or just use markers to decorate. We added red dot sticker taillights and a sticker license plate as well.
Now to get your snail moving! We thought an RC snail rally would be super awesome, so I made a quick trip to Jazams, our local toy store. I found these RC trucks for $17.
One quick note: You’ll notice that the RC truck in the picture above has a nose that sticks out. There was another box, exact same recycling truck, except it had a flat front (see below). Turns out the truck with the flat front held the snail box MUCH better. So aim to find a flat front truck if at all possible!
I removed the green recycle section from the back of the truck, cut a hole in the bottom of each snail box, and then slid the snail onto the cab of the truck like so:
Then we headed out to the big lobby to race our snails! As you can imagine, it super chaotic (we had four running at once). So we waited until a slightly calmer time to video these two racers in action!
Next, turn the box on it’s side and punch a hole in the back. Knot a 15-24″ string through the hole. This is the string that your kid will use to pull the tram car up and down the zip line. Otherwise, it’s going to be YOU doing it. Probably the very moment you are trying to get lunch on the table while answering work texts during a Zoom meeting while also searching for your daughter’s lost LEGO figurine.
Next comes the zip line! I used kite string, but we tested yarn and it works as well. We rigged our zip line on stairs, but a tree in the yard or a tall chair & shorter chair works too. Two very important things: WEIGH BOTH CHAIRS DOWN WITH BOOKS. There will be quite a bit of kid traffic on and around the zip line. Weighing both chairs reduces the chance of nudging or tipping.
Next very important thing: if you are doing this on a stair case, SET BOTH CHAIRS BACK FROM THE STAIRS. Especially if you have two or more kids. You don’t want anyone falling down, or tripping up, the stairs. Below is the minimum I would set the chair from the top of stairs. More so for younger kids and.or multiple kids.
This banana’s going mobile, thanks to its CD wheels and rubber band engine! And why did we rig this fruit to roll? Four words: fusion, bananas, trolls, and technology. This feat of engineering was was constructed at 
Next, cut a toilet paper tube in half, then hot glue it on top of the mini craft sticks:
This creates your “banana saddle,” which keeps the bottom of your banana from interfering with the rubber band motor. Here’s a side view of the finished saddle:
To create the rubber band motor, tightly wrap a brass fastener around the center of a 5.75″ piece of bamboo skewer. You want to prongs to be nice and tight, but make sure there’s still a little room under the head of the brass fastener for the rubber band.
Cut a drinking straw into 3 pieces (two 1.5″ pieces, and one 3.75″ piece). Thread the 2 smaller pieces on either side of the bamboo skewer with the brass fastener. Then thread the larger straw piece onto the other bamboo skewer. Hot glue the straws directly to the jumbo craft sticks, then loop a rubber band onto the center of the longer straw. The underside of your car should now look like this:
Later, you will wrap the rubber band around the head of the brass fastener, then wind the wheel and the axle to tighten the rubber band and prime the banana car’s “motor”:
The car’s wheels are surplus CDs we obtained via donation from various University departments. We pushed a foam bead through the holes of each CDs, then hot glued them for extra security. Slide the wheels onto the ends of the bamboo skewers, then hot glue another foam bead to the outside of each wheel.
The car is ready to go…all you need is a banana! We actually went with FAKE bananas for this project (Amazon: 6 cost $11). Firstly, fake bananas don’t ripen inconveniently. Secondly, fake bananas are lighter, which meant that the cars would roll a little further.
