NEVER PLACE dry ice into a closed container such as a soda bottle. The bottle can explode with a loud bang, damaging your eardrums. ...

Of course that's just an invitation to try it!

EXPERIMENTS WITH DRY ICE

SAFETY NOTE:
NEVER PLACE dry ice into a closed container such as a soda bottle. The bottle can explode with a loud bang, damaging your eardrums. Loose plastic, such as the bottle cap, may fly off, damaging someone's eyes. THIS HAS HAPPENED! (VIDEO) DON'T DO IT!

Handling Dry Ice

Due to its extremely cold temperature (-78.5oC, or -109.3oF), dry ice can cause damage to the skin if handled. Use tongs or insulating gloves when handling dry ice. It is also important when crushing or grinding the solid not to get any of the dust into your eyes. Wear protective goggles.

Popping Film Cans

A fun (and often wild) activity vividly demonstrates the sublimation process. Place a piece of dry ice into a plastic 35mm film container - the kind that has the snap - on cap. Then wait. The cap will pop off, and sometimes fly several meters. The clear Fuji brand containers shoot farther than the gray and black Kodak type. Warn anyone performing this experiment not to aim for anyone's eyes.

Good to know!

 

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 warm water, and close the lid, with the thread attached. Lift the can by the thread, and watch what happens.

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.
