Balloon Powered Toy Car





Introduction: Balloon Powered Toy Car

In this instructable, i will teach you how to make a simple yet exciting Balloon Powered toy car. These are fun to race or just play with.

Step 1: Materials

To build the car, you need a hot glue gun, toy car, water bottle, balloon, (not pictured) knife

Step 2: Making the "engine"

Cut the top part of the water bottle off (see pic), then stretch the balloon over it.  

Step 3: Putting It Together

Hot glue gun the back of the car, then quickly put the "engine" on like in the pic

Step 4: How It Works

Blow up the balloon, pinch the neck, let go. If it just goes in circles it means the water bottle thing is not pointing straight.

    It took me like 20 tries, but it worked! thanks so much. Beats having to make your own car by a long shot!!! I love it! <3



    What do you like? To post comment on your own instructable? lol ;)
    I find the idea really stupid and really smart at the same time. Definitely a project to try to waste some time. Good job;)


    Ah after reading my comment, it do look weird. I mean that even if the idea of making a balloon powered car is.. weird, I still like the project as teh result is epic:)

    well its very helpful, because i need to make one of these for my physics project, so thanks so much to celtics88! my friend and i tried to propel a water bottle with a balloon attached to a straw and it failed, but we'll try this tomorrow
