Okay, time for big list :P, it's made out of...
1 plastic bottle (the body),
1 cork (theres a tiny bit you hold at the back thats hardly seeable),
4 paper clips (3 for the front, 1 for the wire thingy.),
1 toilet roll inside (the bit on the front-bottom of the body thats like a lump.),
1 paper towel inside (I cut it in half, then stuck them together to make it strech long.),
LOTS of paper towels and cellotape (for the outside.)
Thats what I used to make it :D.
