In this episode, Adam and Jamie also created homemade pyrotechnics using water, liquid soap, and methane, and smoke bombs from saltpeter and sugar; demonstrated a way to blow the canister off a stack of Pringles chips by using hydrogen gas, leaving the chips intact; and assembled a dry ice bomb. Adam also implies that more improvised explosives may be tested for a future episode. Despite the "do not try this at home" disclaimers, the MythBusters concluded that Diet Coke and Mentos geysers are safe enough for people to try, even for children (with the exception of getting in trouble by their parents).
