This is so much fun! Make a mini hot air balloon using a Mylar balloon and a foam coffee cup.

Mass comes from energy. The mass of the balloon, in fact, increases.

How much weight does it lift heated. Stabilizing propellors on side and it's the electric car. Except the crashing.

this can be used for future airship design where instead pumping in and out hydrogen gas (the hindenburg disaster was caused by the leaking out hydrogen gas intentionally to decrease altitude and then ignited by electrostatic discharge) this wont happen if you you can permanently sealed the gas from outside oxygen which now you can, all you had to do is heat up the inside using heating rod or more efficient way, thanks for the video this is cool
