Creating Label for bottle Sharp shower ingredients straw Warning label

Knowing Goal: Make a water saving device Materials I used were:  Soap  Vanilla body scrub  Body butter  And some water Method: (1 squirt=1ml)  Put 14 squirts of soap in.  Put 6 squirts of body scrub in  Put 10g of body butter in  Put 200ml of water in  Squash some of the body butter  Shake it  and finally… HAVE FUN!!!!

Understanding My water saving device (sharp shower) is something you use instead of having a shower because, heaps of people have around about a 6-10 (or more) minute shower which wastes a lot of water. I want to stop people from using too much water so, I came up with this thing called Sharp Shower that saves all that water instead of wastes it. You just simply squirt some out of the bottle and rub it all over the body except the face (which you need to wash with a flannel) and let it soak in.
