My brother, friend, and myself did this. The mat ripped during the winter. (yes we were doing it during the winter)

If you want to risk it, put a sprinkler under the trampoline and turn it on while you jump. Much funner.

I used to do this when my friend still had his trampoline.

Soak it in water, and jump to see the droplets hanging in mid air.

Then go higher.

Fun.

Yeah, the only way you can see the droplets is if you jump in the exact middle. It's very fun.
