First of all when a dry ice bomb goes off you have a chance of going deaf and the shrapnel can kill and break windows and secondly you have to be 18 to buy dry ice in san francisco it can also harm ppl around you o and laracrof adry ice bomb wont blow anything near it up all that happens is the compression of gasses from the dry ices expands a container to the bursting point o and there really unpredictaple with timing it could go off 2 seconds after you close or 5 minutes I think it goes under arsen
