Is a dry ice bomb made without any intent to harm anyone or anything legal?

PC12303.3. Every person who possesses, explodes, ignites, or attempts to explode or ignite any destructive device or any explosive with intent to injure, intimidate, or terrify any person, or with intent to wrongfully injure or destroy any property, is guilty of a felony, and shall be punished by imprisonment in the state prison for a period of three, five, or seven years.

So, a friend and I are wanting to make dry ice depth charges and let them go off in my pool. We live in the great state </sarcasm> of California. From what I can tell by interpretation of this CA law we can’t be guilty of anything, because we have no intent to hurt or scare anyone or anything. Am I right in my interpretation?
