Step 1: Prep the Can
You will need a balsa wood rubber band airplane - the kind with the red propeller is best:
Guillow Sky Streak
You can buy these at most toy shops, hobby shops, discount stores, or drugstores for a dollar or so.
But you probably have a broken one already at home !
Hold the Altoids tin on the airplane's body and mark the tin at the center of the motor hook.
Do this on both ends of the Altoids tin.
Step 2: Punch Holes
Punch a hole at each end of the can.
The hole should be centered on the marks you made in the last step.
Step 3: Bend Paper Clips
Bend all four of them open so they look like the yellow clip in the photo.
Bend two of them so they look like the red clip.
These two red clips will be the front wheel struts.
Step 4: Attach Wheel Struts
Use beads or plastic bottle caps for wheels (see intro photo).
Milk jug caps work great. Just poke a hole in the center with a small nail or awl.
Bend the wires to hold the wheels in place.
Step 5: New Engine Mount
If you want to save the airplane stick and not have to cut off a section, you can use a paper clip to hold the propeller in place.
Gently squeeze the small loop on the paper clip with pliers.
This is so the loop will fit in the grooves on the propeller holder.
If your propeller holder does not have notches, you can use a 2 inch piece of the original balsa airplane body, or popsicle sticks, to attach it to the Altoids tin.
