The effect is : Put a burning ordinary toilet paper into mouth.No props are required for the whole process.I saw this effect from a Taiwan magician,and I want to ask you guys more about this effect.My question is that if I put a burning toilet into my mouth ,I'll put it on my tongue in the end.Is there be ok to do like that? I'm afraid there will be Mars after I put it on my tongue, I'm afraid it will hurt my tongue.And I'm afraid the flame hasn't gone out when I put it in. Will it burn to my upper jaw?
