Criminal charges? What kind of police state has America become?
Back in the 1980s when I managed a photo lab, Kodak shipped control strips and other temperature-sensitive materials packed in dry ice. We’d have loads of fun with it, dropping chunks of it into a sink-full of warm water.
Hmmm. Not a great idea to put it in a sealed container. And, isn’t dry ice frozen CO2? Maybe they’ll charge him with a hate crime. Hate against the climate. Anything’s possible anymore.
The charge? Being educated in a public school.
Did he put the dry ice in a pressure cooker?
Don`t Hold Your breath!
Carbon Dioxide is now listed by ATF as a component of bomb-making materials.
Where`s my baking Soda?
If child endangerment is a crime, the people who wrote compulsory attendance laws in some school districts need to be imprisoned as felons.
Unreal.
Dry ice bombs have some serious risks:
- Premature explosion. Burst pressure can occur within seconds, injuring the handler.
- Dry ice is very cold: −78.5 °C (−109.3 °F). The explosion can carry shards of dry ice that had not sublimed.
- The shock wave can be extremely loud and hearing damage can occur even at substantial distances.
- The blast can propel fragments of the container at very high speeds causing cuts and puncture wounds.
- Added shrapnel such as nails, marbles, and metal fragments can cause blunt force trauma to the body.
Dud bombs which fail to explode are a major safety problem. They cannot be left, yet cannot be safely approached. Unexploded bombs can be shot or otherwise ruptured from a safe distance. Injuries are common, with glass bottles in particular posing a risk of serious injury or death.
Sounds like fun! Just be careful.
He should have sent a 2L Coke and a pack of Mentos.

There's safer ways to play with CO2.
