This link that explains the general annealing process without getting too technical http://steamshed.com/annealing%20process.html and here is a YouTube video on the subject by George Goehl https://ai-tube.com/videoai/3wFm11ym8ZN

Some history on Pop Pop boats you look at this Wikipedia link on the subject http://en.wikipedia.org/wiki/Pop_pop_boat they have been around since at least 1891 when a patent was filed by a Frenchman named Thomas Piot.

HOW DOES IT WORK?
Water in the boiler is turned to steam. The steam has a greater volume than the water so it pushes out of the boiler and down the tube. In the tube it cools, condenses and contracts so it is drawn back into the boiler and the process repeats. The action of the steam pushing into the tube pushes the existing water in the tube out the back and that drives the boat forwards. When the steam cools it condenses and contracts so the external pressure pushes the water back up the tube.
If your next question is "why doesn't the boat oscillate backwards and forwards due to this push-pull effect?" try blowing a candle out and then try sucking a candle out and you will see the blow is fairly directional but the suck is not.

Hello.
Hermit Oldguy
I could do with something like that to make a sound isolation mat to put under my kettle, so when I make a cuppa in the middle of the night, less noise will go through the worktop and walls.

it could have made good wheels if it would finish drying

Doh!

Sorry, should have told you, tried to use old silicone like you did, like five years old, and it wouldnt harden, stayed mushy and didnt dry out of the cartridge, dont know why...
JP Slayer Racing
Did you trash it after? Or are you letting it dry more?
