Pop boats - tealights vs firelighters test

Pop Pop boats - tealights vs firelighters test. Had this in mind to try for a while now. Plenty of heat from these firelighters but lots of smoke so probably a good option for a bigger outdoors version. Not sure how long one would last for but I might try making another RC pop pop but more "boat" like than my normal builds and put it on the duck pond for some fun.

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. #GrandadIsAnOldMan #GrandadsOtherChannel
