Molten sand could solidify into glass, perhaps.

I know everyone's waiting for free moving solids to get implemented, so we can make pistons and whatnot.
Once that becomes reality I'm suggesting rubber as a material, so if I for example draw a circle and fill it with gas particles. The gas would pound the inside and stretch the whole circle untill it gets so thin that it breaks.
Maybe also magnetism and magnetic particles that stick together.
Perhaps a button to turn gravity off as well.

hey!,(sorry i am new in this, but its cool) i checkd the page and it looks realy Shi*y because the fire isn well programed, i puted fire+ buble and the buble didnt burnd... but i like the firework dust it could be fine to add it to new version

Sorry for bad english speaking cause i am from chile (southamerica)

that page wasnt This page, it was the "online and shi*y" version of powder toy

I have not made many creations, but I do have an idea that might be useful for constructing circuits and such: a superdense element.

Basically, what it does is always fall downwards, regardless of pressure or velocity. I guess there might be some other effects, but I haven't really thought that far yet.

Due to the randomness of some elements used in circuits, they don't always work as expected. With this element, there would be no worries, since the particles always go down.

Any comments?

sand- when mixed with concrete and water it turns to "Mortar" which is solid concrete

Glass- when sand is heated it produces glass, glass is semi transparent material, shatters when heated to high temps.

Mortar- solid concrete

people- to light on fire and torture, each one has its own health bar as well as a bar that shows happyness
