The forum says ideas that will benefit the game, not individuals.
Toxin is pretty much acid, only weaker. plush is sponge, stars are balls of plasma in the real universe.
have you even played TPT, FireBoom?

Hey im kinda new on this forum, so i dont know if this has been suggested, but this would be a good solid particle to put in:

GLUE: Called Glue. Solid. Any particles it touches is stuck. Any liquid turns it to liquid glue- LGLUE.

LGLUE: Liquid Glue. Turns back to a solid when warmed up.

I have, never thought of those materials like that. I will edit those too of the list.

HDGN: pointless, rejected many times before.
BLOD: pointless idea.
ICRM: what is the point of this?
CDBD: makes sense. good idea +1
JUCE: whats the point of this?
FZJC: whats the point of this?
ANUT: anti neutrons are essentially antimatter subatomic particles, therefore they would destroy anything they touch.
CDLE: have it already. its called wax and liquid wax
GHOL: im sure the black hole would cancel out the white hole, essentially canceling each other out and resulting in no atmospheric change
UBLA: why would you need this when you have many walls?
MCRY: Rejected countless times, like putting more than one stickman into TPT.
GRND: The point of this is...what?
DIRT: Powder, been there, done that.
GCSE: draw more plant therefore making this pointless
CO2: That is an idea with some potential. very, very good idea
LECH: Rejected, or very close to it.
sorry, the truth hurts. im not being an ass. The person who started this suggestion forum stated that all elements should be beneficial to TPT.

Battery powder toy

My not bring in nano mites it would be like anti-matter but they woudn't stop there could be another particle that could be a way to tell them to stop like lava or acid

I allways wanted HDGN in TPT just an example to make bombs you could superheat water and then you got HDGN that is explosive and O2 that is flameable so i dont know why it was rejected so many times (yes i didnt read the topics about it).

Thanks for replying on my ideas. Here is some feedback.

ICRM (Ice Cream) point is to melt when warm. Maybe when melted, it can turn into a Liquid Ice Cream state, which can freeze back into Ice Cream. It's temputure is cold too so it can freeze some liquids too, maybe freezing into Ice Cream.

JUCE (Juice) can stick to some particles, then solify, turning into Frozen Juice, (or FZJC) which maybe protect particles from fire for a short time.

ANUT (Antineutrons) descripion could change to "Antineutrons, destroys any particles it touches."

GRND (Ground) point should change a little bit. Maybe if you pour water on it, a little stalk of plant can grow. It could also maybe cut off electricity.

just type the powder game on web game site dan-ball and take the things in that game in a new version of the powder toy

why antineutrons ? we have antimatter
