Balloon Car

Should be scaled up to 1000%. Better for speed than distance but crushes in both compared to designs from the rest of my class. Crushes in both speed and distance, actually, making it a superior option when scaled up to 1000%. Best not to inflate too much to avoid tipping over, also less air makes it travel faster with just 3-5 puffs. Some assembly is required, obviously. In my experience, it arches slightly to the side, which I couldn't straighten out no matter how hard I tried. The render photos are narrowed for some reason, making them look a bit distorted.
