"Put Put" Boat

A little project my little son and I put together (well, he played with the sticky tape). It costs about 10-20rmb to make and is powered by the principal of thermodynamics = a candle heats air inside a cola can boiler and bubbles power it forward making a loud "put put" sound.

nb. The hull was shaped from a Nescafe coffee can by snipping off both end rings.

Its maiden voyage in "the swamp".

INSTRUCTIONS
be careful when making the boiler!

Fun project.

Reminds me of eighth grade science class. The assignment was to buy a model rocket kit (damn things are expensive), built it, and then launch it on the specified day at the football field which overlooked our school's campus.

First few rockets went great. Get to me and my rocket flies up about 10 yards and then goes wonky straight for the school buildings at 100mph. Boom! Was all we heard...shattered a glass window but nobody was hurt.

The kids behind me were pissed because the teacher suspended the rest of the launches. Ha.

I have no kid, but I like this "Put Put" Boat.

If I put it in the Song Hua River, it will flow away. Broken Heart

Comfortable.

Epic fail with plane No.1, cardboard. duct tape and Cola bottle

2nd attempt

Here its nearly finished..... couldn't find any matte paint in those colours and had to settle for black/green gloss sprays mixed and 30% talcum powder added to get the paint dull.

A 10 Rmb plastic snub pistol had a machine gun sound plus two flashing led's that fitted inside the fuselage and the propeller is driven by an old Walkman motor. The nose area is a metal drinking flask with the paint filed off.. - A/B epoxy was added on the sharp edges (protect little fingers) and the plastic gun's battery holder was split in half and added on the underside of the fuselage.
