Well i always wanted to simulate a bullet on powder toy but the only thing we had there is powder so i thought that a movable metal will be a "group of medium weight particles that falls of screen without separating itself"
and this is what i wanted but also would be nice to have another movable solid like this one
such as movable wax has less weight than the movable metal(meaning that youll need less pressure to move it)but its brokes if it crashes with a strong wall such a goo with 30 dots of in lengthWe could call these element in movable solids classifications under radiactive
META-Movable metal
MOWX-Movable wax
something like that would be cool
please comment i wanna know your thoughts :)
