Part 8 is Step 5, cutting out the pattern and aluminum on the solid lines–carefully. Oops, the words are not on the pattern, but that’s ok, same pattern.Save one of the aluminum strips for a later step.

Part 26 is a congratulations and some final words. I depend on feedback to make the instructions better. And frankly, when you get the engine working it’s encouraging to me to hear that as well. There is a gallery of pictures http://www.sciencetoymaker.org/boat/boatGallery.html of people’s pop pop boats that you can add your boat to. Also, now that you have made a boat, be aware that there is a Yahoo group of people from all over the world who experiment and talk about pop pop boats. Some people are just interested in engine development, or scaling up engines, others in making a beautiful boat for the engine, others in the history. There are nice people moderating the group, there is an enormous archive of tips and pictures, there is no money involved, and it’s easy to join (if an internet dummy like me can do it, anyone can). And, we are mostly older people, but I think I can speak for the group that we would be thrilled to see the work that younger people are pursuing (and you are still welcome if you are a geezer like the rest of us).
The Yahoo pop pop group’s home page is here http://groups.yahoo.com/group/pop-pop-steamboats/

More instructions for a fancier boat body coming soon, I hope.

Part 15 is Step 12, being careful when handling the engine and mixing up a tiny bit more epoxy and using it to seal off the 3 or 4 holes where the straws go into the engine.

Part 4 is Step 1 of the actual building instructions. Are you confused enough? Sorry! The steps are small. This Step 1 is just cutting off the top of an aluminum beverage can.

Part 7 is Step 4, printing out the pattern to print actual size (no fitting to page or scaling) and checking the scale of the pattern to be sure. Then you tape the pattern onto the aluminum sheet.

Part 19 is Step 16, using one of the cooler kind of hot glue guns to apply a thin layer of hot glue over the bendy part of the straws, so as stiffen them so they hold the correct angle.

Part 6 is Step 3, folding the aluminum sheet in half, with a thin sliver of the inside of the can showing so it’s easier to separate in a later step.

Part 14 is Step 11, measuring 1 1/2″ or 39mm from the end of the bendy part of the straws into the small part of the straw. Cut there and apply mixed up, thin, even layer of epoxy to the small part of the straws, but not within 1/4″ or 6mm of the bendy part. Put the straws in the end of the aluminum, but only to within 1/4″ or 6mm of the bendy part. If a lot of epoxy gets on the bendy part, wipe it off, both above and below.

Part 20 is Step 17, cutting down thin birthday candles into 4 pieces, then making a candle holder out of aluminum foil. It’s important to push the aluminum down to the base of the candle, or the candle will go out before burning most of its wax
