IIRC, C4 needs to be detonated. You can burn it, play football with it etc. It will only explode if triggered by a sharp concussion (typically originating inside a block of it), such as you'd get from a detonator.
I think they were pretty stupid to suggest it was as dangerous as chocolate. I can't imagine 150g of C4 doing you much good if you ate it :lol:
