A swimming pool filled with putty = win.
A giant ball pen the size of your average apartment = win.
You wouldn't be able to swim through it and you would drown if you somehow managed to get under the surface.
You could still take wads of Putty and throw it at each other.
That would sting like a bitch if you threw it hard enough.
Now suddenly I want to construct something like a minigun paintball gun that fired silly putty.
Am I the only one who wants to fill a whole room with it and make tunnels and stuff through it?
I want to do that with chocolate cake
I need a ball pit. :C
