Hotknife/Vaporizing Alternative

Sup fellas
I was wondering what are some other home made hotknifeing techniques you guys might use. I of course know about GonG Bells and Nail domes and good old butter knifes just trying to get some other ideas how how i could quickly smoke hash that i press from keef.

put a ball in an ashtray and light it....wait a few and blow it out...pop a large glass over the now glowing hash ball....wait a few and use a straw to get the smoke....

oh gravity or waterfall bong?

I tried gravity bongs a few times with buds but never with hash might have to give it a shot but as for lighting a ball of it, it seems kind of wasteful
