How to build a water rocket launcher without using sprinkler pipe cement.
Here is a supply list:
Two 1/2 inch (`15 mm) threaded pvc pipes 24 inches (about 60 cm) long (I used the dark gray pipe-schedule 80)
1 threaded 1/2 inch (15 mm) 90 degree elbow
1 threaded 1/2 inch (15mm) end cap
pipe thread tape
pack of cable ties (zip ties)–you’ll need 8, I used the 8 inch (about 20 cm) ones
duck tape
adjustable clamp
conduit clamp
tire valve stem (from walmart or autoparts store)
string
scrap board(s)
I don't think Amazon is a great place to get supplies like this but I made a wish list to give others a better visual of what you are looking for at the hardware store. Find it here:
