Line-X is just a commercial brand, you should be talking about the POLYUREA technology which is actually the product of the reaction that you were explaining... video seems sponsored by line-x 👎🏻

I wanted to say that's a bed liner. I didn't knew it's called a bed liner in english so i didn't say it. Glad i learned something new. A friend used something like this on the bullbar of an SUV, the bullbar was glossy and chome .. and seriously scratched. Painted the car in matte and put this plastic stuff the bumpers .... he told me it's a plastic paint used for trunks .. awsome

I particularly like 0:11-0:16. the fact that it resembles little more than a stain on the asphalt afterwards and the sound the watermelon makes are both very pleasing.

I'd like to see and hear it hit the asphalt at terminal velocity.

Author Crushonius ( ago)
1:30 you can see the "coating" looks to be about an inch thick . they sealed the watermelon in 1 inch thick rubber yeah no wonder it survives it

Author Giovanni Di Cello ( ago)

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.
