Anders and his friends want to build a robot. One of them is drawing up a blueprint. Anders is putting together a shopping list. It's a work in progress, but here's what Anders has on his list so far:

With a bit of regularizing, here's what it says:

8 springs
1 digital camera
4 batteries
16 wires
1 switch
1 board of wood
2 battery packs
2 security cameras
19 nails
1 hammer
1 1/4-inch cylinder mold
1 box
1 iron square that's flat
1 blow torch

Let me repeat that last item: one blow torch.
