These are the different types I can do, they all glow, just some more than others.

From the left to right.
clear resin goes in first and little by little the powder is put in, giving it a 'tornado' effect, it also has more powder at the bottom so most of the illumination comes from the bottom up, neat effect.. a little bit of glow powder added in, more liquid looking, not as strong but it still glows pretty well. The last two are how I usually do it, a lot of powder is added into the resin and than the whole thing is put into the bottles, really strong glow but not as liquid looking.

This also gives you an idea of the bottle size, these come in at about 1.25" long. I am getting slightly bigger one's soon.
