Signing UpStep 1: Parts List
- wire
- blue and red LEDs
- 220 Ohm and 100 Ohm resistors
- small toggle switch
- gel candle wax
I got the gel wax from Michaels for $32.23 with a 40% off coupon. There is enough wax to fill three 1.5L bottles.
With $11 worth of wax per bottle and $15 worth of electronics, this project cost about $26 all together. You could get the parts much cheaper online, but I wasn't feeling patient enough for that.
Tools needed:
- glass drill bit
- squirt bottle
- clamp
- soldering iron and solder
- wire cutters
- hot glue gun
- funnel
- sticky tack
- a pot to melt the gel wax
- a food thermometer for the wax

Another alternative to the gel wax would be the water retaining granules available from any gardening or general hardware shop. These come as white crystals and you'd need to hydrate them (add water) bit by bit until they've become a gelatinous mass. Must of the water is locked away in the globs so they aren't as wet as you'd think. Then add to the bottle and shake to get air-spaces between the globs. Downside is the moisture and the electronics would produce corrosion in the LED wires. I found this substance when planning a very similar Instructable using RGB LEDs.
Use "wire pulling gel" instead of a water-based product - it's silicone. No corrosion with this stuff.
You can add fluorescent dye to it, like from a highlighter. Use a UV LED to get it to glow! (remember to wear proper eye protection plz.)
Gelatin (or any other organic substance) will decompose. Yuk. Not recommended.
So going to make this.
One question regarding this step: where are the LEDs in the final design, resting on top of the gel wax ? Or inside it?
Thanks!
Here is a pic of a tupe with the gel set up, no spills or leaks, very cheep!
Good info on the diamond drill bit too. Thanks!
So yeah, gelatin breaks down, so I'm gonna try it with the agar gel :)
Who knows maybe the breakdown process would look interesting if I had to guess I would think a little hydrogen peroxide would slow down the process quite a bit.
I look at these projects as short term things, build it, enjoy em for a while, and then try something new.
Actually I would like to thank you for the idea of the gel because I have been trying to think of something to suspend glitter in so that I can shoot a red laser into and get some sparkling effect the gel may be the perfect solution, (literally and figuratively)
In regards to your question, what about using something like this to inject food coloring?

Great job!
