It would be nice to know what is in the Lego kit to build the balloon car. Nothing is mentioned about the exact pieces to build this car. Why?

Challenge students to build a balloon-powered card that can travel 5 feet! This STEM challenge will take your students through the engineering design process as they brainstorm, design, build, and test with a fun and engaging project.

Start your (balloon) engines! Learn how you can power a toy car with air–and a little knowledge of physics. Then challenge a friend to a race!

Make 4-wheeled, air-powered cars that jet across the floor. Race ’em. Use ’em to play games! For step-by-step instructions visit the Design Squad website.

I have been wanting to try to make a Balloon Powered car for awhile now, but I’ve never found the correct car vessel to be able to make it work.

What can you build with stuff around your house? Find out! See the fan favorite in our latest Top Builder challenge!

Make a balloon-powered car : Make a balloon-powered car . These are fun little things – I remember getting one as a cereal box prize when I was a .

The 1917 Straw Gas Car by MacLaurin using a McLaughlin car didn’t see great uptake I wonder why?

This hands-on activity introduces s at home or college to engineering concepts and the design process.
