The new base is still pretty light weight and easily comes apart for trips to the park. I made the stem a bit higher, so I think the rockets even go higher.
This Instructable assumes that you already own a stomp rocket. If you don't already have a broken one, I'm sure one of your friends with kids does.
Step 1: Gather your materials
I would also invest the $12 in a PVC cutter. I have one from making a bunch of marshmallow shooters for Christmas gifts last year. If you don't have one, you'll need to use a hack saw to make all of your cuts.
I used 3/4 inch PVC since I already had them for a future project that I haven't gotten around to.
Just make sure all your connectors are smooth inside and not threaded.
Follow the image below and cut your pieces out.
Step 2: Putting it together
Drill a hole in the side of one of the elbows large enough for the screw to fit through.
If you go with 1/2 inch PCV, you'll probably need to buy a longer screw so it will go all the way through.
