the working of the cycle

forgot two important points...
1) the cycle works on ropes tied to the cans, not due to friction between the cans and the wheels...
2) and the squirrel can steer the cycle using its tail. The tail fits into the black fins at the back, from where it can turn the front wheel.

The cycle was made using:
primary pieces:
-soda cans
-three sticks
-two wheels
-two axles
-one used typewriter reel
-coir
-tape [very important]
-nails

secendory pieces:
-a rectangular piece of wood for the number plate sort of thing
-fins
-pilleys
-stoppers
-washers

Will work on ONLY the blueprints of a squirrel powered sub now....
