Well, you could use a bunsen burner or an electric skillet.
See video: Leidenfrost effect
This year i am doing my science fair on investigating the effects of the leidenfrost effect. To do so i need to be able to heat up a copper (or metal) sheet up to 100+ degrees celsius and then run water by it. I was thinking of using electricity (a car battery) to heat up the metal, but i have no experience or knowledge in the area. How would I go about heating the metal?
@kelly bramble those are good ideas but i need to be able to heat an actual metal plate that i will bend into the shape of a boat hull, and then heat up or have heated up while submerged under water. Any other ideas
@kelly bramble ok to clarify i am trying to investigate the leidenfrost effect when implemented on whip hulls. The leidenfrost effect is when water evaporates around a surface much hotter than itself. The experiment is that i shall bend a piece of metal into the shape of a boat hull then heat it to 100+ celcius. Then i will measure the water flow rate and compare it to data taken from when the metal was not heated. I have thought of hooking a car battery to it but was wondering if the current would simply be transferred through the water itself as it is a conductor instead of accumulating and heating up the metal. That was just one idea i am very much open to other ideas.
