why it does not glow until now

Who knows what you mean by that question, but Phosphorescent Pigment needs to be charged up by a lightsource before it will begin to glow. So if you opened the box and expect them to glow, they won't. The glow will also be brighter the longer the balls are exposed to light. The glow begins to fade within minutes and slowly loses it's intensity. If you want bright glow in the dark balls during a kids party then get a UV (black) light bulb and keep it on during the party and turn the other lights off. They will glow brightly for a long time.

I don't know why they don't glow. I held them up to light and then turned all of the lights off and still could not see any sign of glowing.

Yes, the whole blue part glows. I had terrible luck with this item as it only worked for a month.

As others have said, if you do not have something plugged into the "IN" jack, it isn't energized and will not illuminate that light. If you do have something plugged into the "IN" jack, it may be defective.

No, it doesn't glow in the dark. But the white web kind of gives that effect.

It glows only at night. I've had for about a year and now we can't get it to light. The positive is that this ball I'd super tough and is great for aggressive chewers.

Mine worked right away! It's just that the light only project upwards on the way and it's yellow not a warm glow!

Mine does not glow in the dark. But still I recommend it. I have had it for a year now, It is a very nice addition in my backyard. I am very pleased with it. It is very well built, It looks and it spins great. I absolutely recommend it.

You have to hold it close to a light source for it to glow well. It will change color when it gets warm.

It gets glowing red, but not a lot of light; maybe some reflection from the metal too. I couldn't read by it, but it's not totally dark either.

Hi James! No the green doesn't actually glow. The color is called fluorescent green because it is a bright green. Rest assured it is dark while sitting in the dark. However, I'm guessing that under a "black light", it may glow. Hope this helps you.

It is Ultraviolet light, which humans can't see, so during the day it is very hard to see if it is on or off, but at night you should be able to see it. If at night the whole bulb is glowing then it is working, if only the top is glowing there is a problem.

You can see it light up and there is a blue glow. It takes ours a second to come on.

Exposure to sunlight or a lamp makes it glow. It won't glow for hours, but long enough for the dogs to find it in the dark. The ball is hollow, no plastic pieces or battery.

Might not be a bad idea, but not required. Try to avoid pointing the light right in your eyes when checking to 'see if it's on'. Instead, point it at a white piece of paper, or white t-shirt. Even in daylight and on 'low', it'll really glow.

In short, yes. It needs to be exposed to light for only a few short seconds to make it glow. I've had this guage for a year and absolutely love it. Much better than the other guages in the market. Would not hesitate to buy again if needed.

If it's a tritium sight you should be able to see it in the dark. That' why their called"night sights". They may be old. The radioactive element lasts about 10 years and .may be dead. I would send them back
