To occur, nuclear fusion requires extremely high
velocity
pressures
temperatures
explosives

Fusion needs to force molecule together

they also need to move fast enough to colide (tempureature) there is a minimum tempurature of 18,000,000 F or 9999982.2222 celcius or

I would say pressure and tempurature, but I would choose pressure because this extremem pressure could make the requiared tempureature

B, if it was a lower watt she could put it in for her normal time and not burn it
