Boil water inside a small container with an arduino I am currently working with a sciene/electronic project where i need "steam". In order to create steam i need to boil water and i plan to boil it inside a very small container [around 5cmx5cmx5cm]. What i want to do is to control this with an arduino but I am very unsure on what step i currently need to make. Are there any "heating-up" modules out there? Or would I need to order a mini-mini kettle and connect that to my arduino? 

I am very grateful for every advice i can get because as u can tell i am a bit confused as of right now!
Try to find a boiler pot on electricity (I doubt you can heat water to boiling temperature with like 5V (unless you use many amperes).

Use a relais to switch it on with an Arduino.

Use a temperature sensor (0-150 degrees or so) to decide when to switch it off. 

Warning: Get first some electrical knowledge before you start with >200 volts projects since it can be deadly. And boiling water can be devestating for skin and your Arduino.
