Yea PE tubing can be melted with a lighter flame over time. But the bowl's only lasted about 4-6 hits and none of the device was hot except for the bowl-head(as expected). I believe the water does a good job keeping the temperature low.
Yea it wasn't anything permanent(already disassembled and cleaned) it got me nice and toasty though
.
I'm sure there will be more DIY devices in the future. Reminds me of being a kid haha.
