TOPIC: pop-pop toy boat building

check out these websites you and your kids and grandkids can have a little fun building these little boats,im sure alot of you can even improve on the designs.
in this link be sure to look all the way to the bottom,there you can see how to build a carbide submarine made from soup cans.
even i might play around building one and i dont have kids,lol,heres the 1st link. www.pop-popboats.com/go.pl?go=www..sticksite..com/putputboat/&referer=http://www.pop-popboats.com/-/newest_additions/&lstref=11
ill be back with the 2nd link,and it has all kinds of links like this.
by the way i didnt write these ,i just found them on the web and thought it was cool,john
here is the 2nd link,it has alot of what are called put-put or pop-pop boat stuff links on it,john

Looks like a very cool project and a great parent/child (or grandchild) project. Even the propulsion system is ingenious.

The submarine with the Carbide propulsion is a little scary. I had a carbide canon as a kid and that seemed a little dangerous. Do they even sell that stuff anymore?

John, if you build one of these, I expect it to have fins.

That's cool.. I picked up this little putt-putt boat somewhere a few years back. It's a hoot to play with. Uses a birthday candle laid flat inside. The boat is about 5" long.

Very cool... I say we have a put-put boat building contest on here this winter when our 'real' projects are all laid up

I love his video- it even SOUNDS cool!

todd ,yep definatly will have fins,i might make a couple but out of better material,just for fun.
doug thats pretty cool.
andrew i like that idea!especially if we can make them out of anything we want,or hw we want,it would be cool to the designs everyone makes,im in.john

this is what a fellow named steve(i dont know his last name)(on ebay,"poppopboats"said ,on how these boats work,he also says that olive oil with a wick works great.
quote....After filling the thrust tubes with water, a small candle or wick with olive oil for fuel is placed underneath the rear of the flash steam boiler. When the water droplets in the boiler flash to steam, the pressure created pushes the water out the ends of the tubes, which provides forward thrust to the boat. As the steam cools and condenses it creates a vacuum, which draws water in for the next cycle. This happens in a quick resonant pulse, which can be seen in the ripples behind the boat. The thin brass stock on the top of the boiler flexes up and down providing an enhanced pulse and putt putt sound, which adds to the drama. The forward pulse is much stronger than the opposite action of the water being drawn back into the tubes. This is best understood in considering that you can blow a candle out, but you cannot suck it out, as the volume of air comes into your mouth from a multidirectional path.



From the technical to the vintage toy enthusiast, everyone has loved putt putt boats since the late 1800’s. Call ‘em what you like, pop pop, putt putt, tin toy steamboat, I love them all. I never tire of watching and listening to them run.

i never knew these ever existed,very cool even for a grownup,like me,lol.john

And a video:

andgott, that is a very good idea on the toy boat contest. lets get this going it should be fun. frog these are just push toys, or with a string they could be pull toys.

chinewalker ,great fun wathing that,cool boats.
frog i agree,and they should be made from scratch wthout a kit,in your own design,except for the propolsion,lol.
and take progress pics,so dads moms,and grand parents can do the same with their kids.
