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.
