Elm Ice and Oil

Hero's Engine - Using a push pin, or a straight pin held in pliers, poke two holes into opposite sides
of a film can, near the bottom. The holes should be off - center, like pinwheel rockets. Tie a loop in a
length of thread. The loop should fit loosely over the cap of the film can, so that when you loop it over
the cap, and snap the cap onto the can, you can hold the can by the remaining length of thread.
Place a small piece of dry ice into the can. Then quickly add some HOT water, and close the lid, with
the thread attached. Lift the can by the thread, and watch what happens.

Inflate a Balloon - Grab an uninflated balloon and force the neck open with the index and middle
fingers of both hands, stretching the balloon open. This will allow you to drop in one or more pellets of
dry ice. Tie the balloon closed. Set aside, and observe for awhile. Better yet, drop the balloon into a
pond or swimming pool. This will help supply heat to the dry ice. At first, the balloon will sink, but soon,
as it begins to inflate, it will rise to the surface. If you manage to put enough dry ice into the balloon, it
will eventually reach the bursting point. Again, this is lots of fun if the balloon is in a pool.

Singing Spoon - Press a warm spoon firmly against a chunk of dry ice. The spoon will scream
loudly as the heat of the spoon causes the dry ice to instantly turn to gas where the two make contact.
The pressure of this gas pushes the spoon away from the dry ice, and without contact, the dry ice
stops sublimating. The spoon falls back into contact again, and the cycle repeats. This all happens so
quickly that the spoon vibrates, causing the singing sound you hear.

Coke Bomb- Too dangerous for geneal public knowledge, ask us in the next time you come in.
