This is a Origami Paper Tank and you can make a lot of them and make a war scene. You can also make them for your kids to play with.
Step 2: The Origami Fold
Take a corner and fold it to the side and make a crease. Unfold it and do the same to the other corner and unfold. Now you should have an "x". Take both sides of the "x" and push them in, then make a crease so it should look like a triangle. Repeat the same to the other side.
Step 3: Making The Wheels
Now turn it so both points are pointing at left and right. Take both flaps and fold them to the other side. Then take the top side of the paper and fold it to the middle. Now take that side to folded and fold it up and unfold the flaps that you folded to the other side. Do the same to the other side.
Step 4: Making The Tank Appear
Pick one side but your only doing this one time. Take the corners and fold them down and leave a gap in the middle. The gap is going to be where the barrel is going to be. Then flip it over and fold the side you've chosen back and fold the other side back on top of the other side.
Step 5: Locking In The Flaps
Unfold the side you just folded and there should be two flaps. Take the two flaps and put them under the other side's flaps. Then flatten it and there should be two flaps not locked in yet. Take one of the flaps and bring them to the side. There should be a little pocket in each side. Now stick the two flaps in that pocket.
