Cars are cool! Especially cars that you make yourself.

We had our StoryBots take this STEM Challenge and you’re gonna love what they came up with. The best part? It’s a STEM Challenge that anyone can complete!

Challenge: Create a cardboard tube car and design it’s power source.

Let’s look at what you need, the instructions…then let’s check out our results!

Step 1: Find some rolls

Grab some cardboard paper rolls (aka toilet paper rolls). I grabbed five since I was going to make one for each StoryBot! This is the first step because I always forget to save them…just give yourself some time to collect these.

Step 2: Gather Supplies

Get the supplies…don’t limit yourself to traditional
items! Maker spaces need the most random things. I used markers, glue, pipe cleaners, and construction paper.

Step 3: Paint

Paint the rolls your favorite color! I painted one tube for each StoryBot!

Step 4: Create an opening


👩‍👧 This is a grown-up job.

Using scissors or a craft knife, cut out three sides of a rectangle, leaving one side intact. Fold the flap inwards and secure with a paperclip.

Step 5: Design Your Engine!

Here’s where the planning comes in. What powers your car? We decided each StoryBots’ car would probably be powered by something different. Take a look at what we came up with. Hopefully these will inspire your own creations!
