Horizontal View TNT Cylinder (IMAGE)
Caption
This is a horizontal view 2m across of a 2 kg TNT cylinder being top-detonated. The detonation products expand into air at a rate of several mm/usec, with a shock at the surface of the products (the explosive near-field). As air drag slows the detonation products, the shock detaches and travels through the ambient air - the explosive mid-field.
