Christmas comes once a year but not on MythBusters! Is it really true that leaving some Christmas lights on your tree overnight could cause it to heat up so much that the tree bursts into a ball of flame? Meanwhile, Kari, Grant and Tori investigate a frontier technology that if confirmed would take off in a big way. Anti-gravity is the holy grail of science. But is it science or science fiction? With a flick of a switch can you simply turn off gravity? And if that wasn't enough, in "Vodka Jellyfish," Kari puts her life on the line with a final shot at a vodka myth. Is it true that vodka can cure the pain of a jellyfish sting? There are screams, torture and tentacles! .
