This Experiment Should Only be Completed Under the Supervision of a Professional
Materials you will need
Empty small water bottles OR large pop bottles.
Dry ice which you can get from your local gas store.
Readily available hot water.
Make sure your tap can produce hot water
Run the tap for a while, then once the water is hot enough: take your bottle, unscrew the cap and fill it with hot water 3 quarters of the way to the top. Screw the cap back on to keep the water hot in the mean time.
When you're ready to detonate, take your bottle of hot water, unscrew the cap, then place the cube of dry ice inside the water bottle
Shortly after, you must tightly screw the cap back on the water bottle when ready to detonate. This will give you a couple second window to throw your bomb until it explodes due to the pressure of the dry ice expanding inside. This should only be done under supervision of an adult! You should always handle dry ice with care since you can severely burn your hands when using it.
Not enough water was added to the bottle, causing the pressure to build up but not reach an explosion. The solution: Use a BB gun to shoot the bottle in order to relieve the pressure. DO NOT TRY THIS AT HOME.
Let's explode another medium sized bottle with 3 cubes of dry ice
You should always be at least 10 meters away from the dry ice bomb once it has been prepared and thrown. Even if it looks like the bottle won't explode, don't walk close to it since it could still detonate at any moment.
