The balloon powered car is intended for teachers and students as an aid in explaining the terms "energy conversion" and "Newton's 3rd law".
To make a car you need:
-3D printed car model
-3D printed wheels (4 pieces), wheel V2 (3mm hole, 30mm diameter), wheel V3 (2,5mm hole, 30mm diameter)
-Barbecue skewers (as axles for connecting wheels)
-One balloon
-any glue (we recommend hot glue)
