Can you burn yourself with the goblet of fire?

Answer 1

Probably. There is fire in the Goblet and you will see that no one actually puts their hand into the flame, so it indicates that the flame would burn them if they did so. They all throw/drop their names from above the flame, and when the names are selected they fly out of the Goblet rather than being manually picked out. Also, the parchment with the names on them come out smoking, which indicates heat and burning.
