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 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.

To start out put the candle flame in the middle between the front and the back of the engine.
