Do the different colors of the glow sticks come from different chemicals or is the plastic of the tubes different colors?

Mine has a black plastic piece not red like the picture on the left surrounding the 3 LED lights. The black piece does not glow, however the 3 LED lights are quite bright.

All were black lights. I have used them with UV sensitive ink and clay for demonstrations with kids, and they work fine.

I found them on the crayola website. They are called Color Explosion Glow Board Refill pack.

Although the word "neon" is often used interchangeably when other gases are used (such as in a "neon" sign that may incorporate several different colored gases). I'm giving my best guess (science teacher) that it is actually Neon in the tubes because Argon is more of a purple color. Neon sign artist will mix gases though and therefore it could be a combination of gases also. The color in the tubes I have is an orange. I chose this because I was more interested in having skin tightening and controlling dark spots and my internet research seemed to imply that the Argon tubes were for acne and moles. I seem to notice a difference after several uses but I'm still conducting my own experiment. I'm waiting for more data before I give a true review of the appliance. http://wiki.answers.com/Q/What_are_the_Colors_of_inert_gases http://chemistry.about.com/od/imagesclipartstructures/ig/Science-Pictures/Noble-Gases.htm

You wouldn't notice any major physical difference in the glue sticks at room temperature other than color. I believe they have a higher melt temperature and so when bonding plastics they soften and bond to the parts much better. I had had a problem with some of my custom plastic constructions coming apart during hot days in the sub tropics before I discovered these Steinel sticks. Those problems are now gone so I am very pleased with the bonding properties of these sticks.

I believe that what you received may, in fact, be a different device. There are two types of gas used commonly, with very slight differences in the frequency and power output. Violet is the preferred, due to less UV output.

Not sure. But the black and red one i got were plastic. They looked disposable. If plastic was a little stronger i would recommend. I think its selling the look of the bowel not the quality. All and all. You get what you paid for.

There was a mixture of colors. Some were bright and some were pastel. Some of them had glitter in them.I used them with a nail file as favors for a baby shower. I was very satisfied with the product.

They are plastic and I love them. The show many colors that change. I liked mine so much that I bought one for a Christmas present.

It's hard to tell if it's regular resin or latex, personally i would not buy them as they do not glow at all, just regular bouncing balls. Note that they are small enough for a baby to choke on, so if you have a small one, you should be careful with them.

No. There are a variety of colors, but no glow in the dark according to my kids.

I haven't seen any glow in the dark rubber bands. I am thinking that Neon Colors glow in the dark, don't recall seeing any of those in rubber bands. You can check further into this.

It doesn't say on the packaging. But I'm guessing they are made from different materials to get the different effects. They are really good.

They are not as bright as plastic blocks. You can slightly see the woodgrain through the paint on the blocks. I bought them to go with some Melissa & Doug pattern boards and the colors matched nicely.

Yep. Every color glows in the same yellow/green color. I was under the impression they would glow in the same color as the paint, but they all glow in the standard glow-in-the-dark green color.

Some filled with Neon, some with Argon. Only use those tubes filled with Argon. Thats the original giving the violet healing vibration.
