The brace that isn't supported the sprinkler valve isn't really structural, so it can be flexible. And the launch button box can be flexible too since kids kind of throw them around. With 3 nine volt batteries inside, there is enough weight to break PLA or PETG pretty easily. Cut two 13 inch long pieces of 2 inch pressure PVC pipe. These will make up the main portion of the compression chamber.The maximum range is achieved when the angle of launch is 45 o. The range increses as the angle changes from zero to 45 o and decreases as it exceeds 45 o. (max 2 marks)

Connect the speaker wires to the sprinkler valve. The positive and negative do not matter for the valve. Lippisch Ente."

Measure the circumference of the widest part of a small inflated balloon with a tape. After performing the experiment, measure the distance traveled by setting a ruler along the straight string. Repeat with bigger balloons having greater circumferences at their centers. Tabulate the results and plot it on a graph taking the circumference (or radius) along the X-axis. How does it change?

I am not going to mangle the explanation here, but rather link to a good source on it: https://rayshobby.net/wordpress/understanding-24va... The punchline being this: "the issue is that under DC there is no reactance, so the coil’s inductance plays no effect at limiting the current" -- this observation means that the solenoids can easily overheat or burn up sending them VDC if we hold down the button too long (at least this is my understanding).

Connect 3 9v batteries to the connectors, and put the batteries into the pipe. Put the 1.25 inch caps on the pipe to protect all the batteries inside. No glue is required because you'll need to change the batteries eventually. Drill a hole in a the 1.25 inch PVC cap for the button. The size needed will be different for whichever button you use.I used an 80 PSI pop-off (also called a safety relief pressure valve). 80 PSI should be more than enough pressure, since the two inch pipe designed launchers never really need to go above 30 PSI.
