Part 10 is Step 7, acurately folding the edge flaps the rest of the way over with a credit card or something like it. Then you need to pound it (not rub it) flat. Be careful not to kink it.

Part 11 is Step 8, using a thumbnail to open up the end of the “pocket” a bit, then pinching the end of the long part of a flexible straw and pushing it in. Then the long part of another straw. Push all the way in, but not so hard them split the other end.

Part 13 is Step 10, is actually gluing the aluminum so it keeps its new shape. You should watch the whole step before starting because you only have 5 minutes once you mix the two parts together (less if it’s hot). You should have equal parts and mix thoroughly. Dab it on the silver parts even where the silver disappears, especially the ends. It’s really important to push the epoxy in between the folds of aluminum with the strip, for strength and to prevent leaks.

Part 17 is Step 14, making a cardboard angle tool to set the angle between the aluminum boiler and the straws. You saved the pattern that printed out with the boiler pattern way back in part 7, step 4, didn’t you?!

Part 23 Build a Putt Putt Pop Pop Boat s20 tips
Author: admin
Part 23 is Step 20, some tips when you’re finished using the engine, like wiping off the carbon from the candle. Also, using heat to remove what’s left of the candle and affix a new one so it doesn’t keep falling out. Now is the time to decide which kind of boat to make for your engine. OOPS! I only have the simple flat boat instructions done.

Part 9 is Step 6, finding a sharp desk corner, lining up the dashed lines with the corner, and making clear fold lines on the dashed lines of the pattern. Your thumbs should be together, and press really hard so you see clear fold lines.

Part 25 is Step 22, making the boat go faster by restricting the straws a little at the end, just like real jet engines and rockets. Finally you can tell the control freak (me) to go soak his head, and you can break loose with experiments.

Part 21 is Step 18, the step when you finally get to power test the engine! You don’t need a boat to power test the engine. You must prime the straws every time you use the engine. And the first time you use the engine you should slosh some water around inside the engine so the little droplets of water can flash to steam and get your engine going. To start out put the candle flame in the middle between the front and the back of the engine.
