I've been wanting to try the Fairies in a Jar project for awhile. The following 2 pictures are what are featured online. So sparkly right? The instructions are so easy! Just get a glowstick, crack to activate, then cut the end off and splatter inside a jar and add 'diamond' glitter. The only info I could glean on diamond glitter is that it's the white & iridescent kind, of which I have plenty. I also had some glowsticks left over from the 'toilet paper roll eyes' project last Halloween.
I cracked the blue light stick and shook it out and around this jar, then sprinkled in the glitter. While it did stick to the jar and was sparkly, it was only so due to the external light source in the kitchen.
In the kitchen with only one light on over the stove and no flash. Blue is real pretty, glitter picking up the stove light.
Looking at the bottom, taken outside at dusk.
Dusk shot too.
With flashlight pointing straight down into jar.
Just flash.
With a candle inside which had a cool effect but you couldn't see the blue anymore.
Looking inside with candle light. That's as close to twinkling fairies as it gets.
I'd say it only twinkles with a light source that's outside the jar. It was pretty seeing the blue jar, but the glitter definitely doesn't sparkle like the internet photos show. The twinkles are obviously photoshopped in the first picture and upon review of the second picture, it looks like the glow in the dark paint was dabbed on in dots; it's possible there is glow in the dark paint that has glitter in it.
The ironic thing was that as I was outside taking the pics, there were lots of real fireflies in my yard. I'd say just use the jars to catch and release actual fireflies, rather than make a mess with this project!!!
