Since you were showing the molecular structure you could have added something about where the heat was coming from. Electrons migrating or just changing energy levels?

Author sadclownairraid Arka-9 // MC FAX ( ago)
Impressive stuff, but to be honest thats like a 3cm thick coating on the watermelon. I bet if you wound the same thickness of duct tape around it, it would also not break.

Author F2 Cameron Khanpour ( ago)
I know this might be stupid to ask, but in the beginning of the video, Veritasium said the watermelon was " free fall for a full 3 seconds..." (0:13 - 0:15), but i though free fall was the falling of an object when gravity was the only force behind it, so if I am right, then the watermelon was actually not in free fall because there was clearly air resistance in the falling of the watermelon. Please let me know if I am wrong and explain, thanks.

Curious, then if the impact was sufficient, and the watermelon rind smashed to small pieces on the inside, would there be any outward show?

Author Ty Shank ( ago)

Author kibidk ( ago)
That's not a "coating" - that's a thick layer. And seriously - you consider the watermelon to have "survived" a 100km/h impact?..........

are all your videos ads now?

Author Zenon Rychter ( ago)
Great video, again.
One clarification, though.
The surface-reinforced (coated) water mellon, after hitting the ground, goes sideweays,
flattens rotationally symmetrically, as the video show in the segment 6:00+.
This creates large, elastic hoop stresses, along the stretched equator, in the reinforcement.
Theses stresses make the ball bounce back, not the vertical (meridional) stresses
the video shows as arrows. The meridional stresses are insignificant relative to hoop stresses.
This is because it is hard to stretch (equator here) and relatively easy to bend (meridians here).
It's the equator that does the heavy lifting.

1:02 Use that as a basket ball.

Author Jeremy Thelen ( ago)
Reminds me of 2 things, that have 2 parts that are mixed:
1. Epoxies - those 2 part glues that are really strong.
2. Icynene spray foam - use to install this 100 to 1 expansion soft foam that also came in 2 barrels from Canada.
Was sprayed at high pressure, and also at 150 degree temperatures. Very permanent on everything it touched, except your skin - you had to take a razor blade to get it off.

So if we spray this stuff on spaceships... we should be ok?
