It's like a tag outside the cup. The temperature makes it change color, but once it changed, it wouldn't change back immediately as youn pour out the water because the cup is still hot. It will change back unless the cup is cooled.

Liquid. Verymuch like the spray kids use on halloween to change thier hair color.

Use Mineral Spirits. Laquer thinner is BAD stuff on some plastics and nervous systems

The product oxidizes into the designated shade. Basically, it changes color once you apply it to your face and let it sit.

Plastic, but why they would do this I have no idea. Everyone in the industry knows plastic is toxic.

I have noticed they can change color over time. I don't know if that has any impact on their effectiveness.

None! This brand was horrible, it didn't dye my dog the color it said, which was black for me. She came out green and then orange. It also had a bad reaction on her skin. I wouldn't refer this product to anyone.

I'm using it to remove black spots from an oak table. Spots made by water. Haven't used it yet so I don't know how much it smells/toxicity

You dont. The crystals inside draw moisture through a chemical process. When they change color to pink you plug it into an outlet and the electricity drys the crystals.

There are several color choices. The Java is a good one to darken lighter items already stained. I used this on staircase railing to change the color from a golden oak to more of a walnut.

as its non toxic I have only used water, lotion, oil, and combinations of them. I make a lot of face paint with them

What you want is the one one filled with Argn gas That gives you the violet color. The orange came out as a result of neon gas . You don't want that one

I returned and refunded it. It's toxic. Why poison the kid? I did air it out and even washed it but it made no difference. Get rid of it!

It just soaks in to the crystals...so eventually they get yellowish colored, and then you know it's time to change them.

I never even thought about that. Like most colors, there is a color lens that give out the color. The set up was a blue out put, so you might call the maker and see if there is another color lens you can change to.

I believe that it is toxic. It contains a Cyanoacrylate and has some kind of a petroleum in it. It is catalyzed with water, but it does have all kinds of skin contact and "keep out of children's reach" warning label. "Seek medical help if ingested" and so forth. So, Yes, I would say that it IS TOXIC. GREAT GLUE, though and waterproof. Hope this helps.

I notice on the container that it says to avoid contact with eyes and skin, so its got to be toxic. It also says to throw in "trash," nothing mentioned about recycling and there is no recycling symbol on the container, probably because the contents are toxic. This is too bad if it is not recyclable because each time you use one, the big plastic container must be tossed in the trash. It is made in China. It would be worth a call to the 1-800 number to ask this question.
