Explore mass, thrust, drag, friction, and more with this hands-on engineering challenge from the James Dyson Foundation: Balloon car race. Mechanical engineer Shanice O’Mara introduces the DIY balloon-powered car activity for kids of all ages, including teens and adults, as well as the record-setting Bloodhound SSC Car that inspired it.
She meets with three Dyson engineers who share their balloon race car designs in a car race and a next-level demonstration.
Supplies to start with: A balloon, a plastic cup or bottle, straws, thread, and rubber bands.
Previously from Dyson: Spaghetti bridges, a DIY engineering activity for kids (and adults).
