For a magical Halloween display I illuminated the mana potion by placing a battery-powered LED light underneath it.
I cut the top off of a clear plastic cup and Mod Podged white tissue paper over it to create a diffusing shell that the LED sits within.
Never go Out Of Mana again!
Materials (for one mana potion):
1x [Yaley Gel Candle Wax]
1x [Yaley Candle Dye Block - Blue]
1x [Glass Vial] (with stopper)
* At this point we realized we did not have enough gel to fill the entire vial and decided that a half-filled vial would look stupid. So, after pouring in the gel, I rolled the vial around to cover all of the sides thoroughly to give the illusion that it was full. If I did this again I would make enough gel to fill the entire vial.
3. Tap to try and remove bubbles - do not stick anything in there because it will just add bubbles. Leave the vial alone and don't touch it until it has cooled and turned to a "solid" gel. If you move it at all, you will get bubbles or the gel will creep up and stick to the sides instead of settling correctly.
4. Add the stopper.
