Here's the supply list:
- 1 tube of superglue
- 1 roll of tinfoil
- 1 straw big enough to fit around your launch rod
- 1 deck of playing cards that you don't mind parting with
- 1 C rocket engine
- several rocket engine detonators + plugs
- 1 electronic detonator (and necessary cables)
WARNING: This is totally dangerous. I didn't die, but you might. It is NOT MY FAULT if you hurt yourself following these instructions.
Step 1: Building Yourself Some Fins
Now you can need to do a little bit of measuring, but nothing too complicated. Take one of the folded cards and put it perpendicular to the other, forming an L. Mark off the edge and cut it away so you're left with one square-ish shape. Repeat with the other folded card and, if you've done everything correctly thus far you should be left with two pseudo-squares.
Take these faux-squares and cut diagonally across from the curved corner to the corner directly opposite. You should now have four fin shapes, congratulations. Now onto the difficult part, attaching them.
Step 2: Attaching the Fins
I've attached a template PDF to this step, I would recommend printing it out and using it as a guide when you're gluing. Superglue is really REALLY good at bonding cardboard, so you're only going to get one shot at this. Line up your engine, apply a small amount of glue to the edge of the fin, and take the dive. The first fin is the easiest, but every other fin has to be positioned as accurately as possible to prevent the rocket from spinning out. Again, just take your time and it should be fine.
Once you have all the fins loosely attached, apply a liberal amount of glue to the seams. You do not want one of these falling off mid flight.
Put the rocket in the sun to dry, the next step is going to take a while.
Step 3: Sculpting a Nose Cone
Once you're satisfied with your cone, just glue it onto the end of your rocket. Mine happened to fit perfectly within the cardboard tube, but it's fine if yours is a bit larger. I applied a good puddle of glue around the cone and waited for it to harden, just to ensure the cone was attached snugly.
Step 4: Attaching the Launch Lug
Once your launch lug is dried on, you're all done. FInd a good open area to launch it and prepare the detonator.
