I am trying to create instant boiling water using a chemical of sorts, so that it can be consumed by a human. For example; someone could make tea without a kettle or any available water heating systems.

It must be completely safe and if possible, leave no bad tasting remains. Preferably, the chemicals used would have to be easily accessible and stable in its bought state.

I am in high school and just want to do a cool science experiment. I guess this could have endless potential applications. I am also open to other ideas, like making a disposable bottle, that when you twisted the lid, the water would heat up as the chemicals dropped down or the bottle itself heated up. Just any way of doing it would be awesome.

I saw this page but is wasn't consumable ideas:

Can you heat water with additives?

Thanks, Charles

Adding something to water that heats it to 100°C and leaves only water is of course nonsense.

A self-heating cup is easy: You take a double-walled beaker, fill the space between with two compounds that react with great heat but no gas formation, separated by an extra wall with a valve.

Google the self-cooling beer keg. It works very similar, only it gets hot outside, not inside.

Or just google "self-heating coffe cup".
