So many who think bombs are the way to go. They are not.
None of the following is a good idea, either.
Fun facts I've learned while working for a living:
1.) A bottle of coca-cola, or any sugary drink, will ruin a concrete pour.
2.) Diesel equipment doesn't like water, gasoline, or eggs in the tank.
3.) There are two ends of a telephone line. One end is at the building. The other end is in a box nearby that nobody is watching.
4.) A battered hard hat, old steel toe boots, a dirty yellow safety vest, and an air of confidence will turn you invisible.
