I don't know if this has been said but can you make a wall that is indestructible but allows pressure to pass through?

Add magnets

I second magnets, with the possibility of adding gears and stuff to powder toy. Combine magnets with wire and allow them to spin and you get a motor!!!

maybe make some stuff like an explosive that explodes faster. another idea is cartridge which is like on Phun where u draw a shape and it becomes a case. like moveable metal that obeys gravity. get what im saying?

Precious Metals/Minerals, Like Emerald, Gold, Silver, and Obesian.

Magnets have been rejected several times


No movable solids

Can't see a point?

Already there... "Blocks particles allows air" or "absorbs particles, allows air"

I think that it would be nice if lava and molten wax and all of those other happy liquids could vaporize or dissappear at high enough temperatures.

I have a bunch of ideas, ranked from important to unimportant.

-Gel: A liquid-solid. Objects that sink in it sink slower. Also neutralizes fire, acid, etc.
-Multiplex: A hard plastic that is almost indestructible, except at very high tempratures.
-Floodlight: When fed with energy gives out a lot of photons.
-Ink: Can dye a material a different color (Changes color every different temp)
-Electricity: A bolt of electricity that can jump from conducting rods (see below)
-Rubber: Causes anything that hits it to bounce

I think if there was a undo button and a 2x speed button that would be great.

Spark.


Rejected

I would love to see some sort of powder that has a weight dependant on its temperature.
e.g. At -273.15 degrees it floats like GRAV with no velocity and the falling speed of the powder increases with the temperature, is this possible?
