My First upload,
A tower that can relese water by a pull of a switch to defend against creeper explosions!

It also can be used as a decroation, because the water can be switched on and off.
I have done some small furnishings which can easyily be removed to create it the way you like.
The tower can still be expanded, i left the top like this so you can create more floors and make
the tower the way you like it!

I will be expanding the tower later today, to make it more effiecent at holding out those pesky mobs.
