This mod adds the paint gun from Aperture Tag: The Paint Gun Testing Initiative (a Portal 2 mod) to Minecraft, as well as the two gels that it shoots.
Holding right click makes the gun shoot propulsion gel, it makes you go fast when you walk on it.
Holding left click makes the gun shoot repulsion gel, it makes you bounce when you hit it.
The gels will despawn over time so you don't have to worry about cleaning up after yourself. If you still want to quickly get rid of a bunch of gel, you can right click it with a wet sponge to clear a large area.
