Defensive tech

L.I to build a fort to defend from others.
On Tuesday we had a special guest which was Mr Ching or Isaac. He came and talked to us about war technology. Now we had talked about different types of war tech and they are: Dumb bomb, warheads, dynamite, C4's and mortars. Now Dumb bombs are bombs that when they are shot of dropped then that's where its going to go.

Warheads are missiles that can be controlled which is also called a smart bomb or a guided missile. Dynamite and C4's are things that you want to use to blow up small things like houses bridges. Mortars are the same as dumb bombs. At the end we got to do a challenge that Mr Ching (the guest) wanted us to do, and that was to build a fort to protect a helicopter from a shock wave.
