Small coil pop pop Fillets of Anchovies tin. I wasn't going to use that little tin again as I thought it was too small but then I found this short length of copper tubing and had an idea. Not as successful as I hoped. BUT a simple modification and much improved in PART 2

Here is the link to DaveHax tutorial which I found excellent
sciencetoymaker has a full step by step tutorial series on putt putt (pop pop) boats starting in January 2009 with episode 1 here
Here is a good video on tweaking the speed of these boats
This link that explains the general annealing process without getting too technical and here is a YouTube video on the subject by George Goehl

Some history on Pop Pop boats you look at this Wikipedia link on the subject they have been around since at least 1891 when a patent was filed by a Frenchman named Thomas Piot.

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.

These pop-pop boats seem to be like little distilleries. I remember my Father telling me about my Grandfather and how he used to make whisky during the war. They used a thing called a worm which was made from copper pipe and coiled through cold water to turn the steam from the boiling whisky alcohol mix back into liquid. Then you have distilled whisky. They were probably going "POP-POP" once they drank it. :D
Grandad, you are getting obsessed with pop pop boats!!!

If you push a length of wire through the tube, it'll stop it crimping while you're bending it. and with a bit of grease on the wire, you'll be able to get the wire out afterwards.
If you use a half-used tea-light instead of a new one, it'd be lighter.
dang , cant be cheeky with this one . not a blue ribband contender but still she goes .:)
