You could add a switch on the side of the jar so you don't have to open up the jar to turn it off. Plus, it will save on battery life. Make sure you waterproof the wiring on the switch, or it will compromise all your hard work.

you know, a better idea may be to make it solar powered, that way the battery wont run out

Awesome instructable! I've lamps like this before in Spencer's, but there's just so much more satisfaction in making your own, you know? Besides. The green glow in your version is consistent, while the Spencer's version had its illumination strictly from the lightsource and not the liquid as well.

Anyways, I've an idea with keeping the alien fetus suspended in a more aesthetic manner. Maybe, while implanting a fishing weight into the bottom, you implant a pocket of air into the top of its head? The fetus will stand upright without having to be attached to any part of the jar, so it could drift and float too.

I wonder if simply using several small "glow sticks" glued to the underside of the cap would also work. Could be a lot less work and completely waterproof.

Glow sticks won't give the same effect (plus the aforementioned short life) as shining UV light into fluorescent liquid. It may not show well in his photos, but the liquid itself is glowing. The only way to get the same effect with glow sticks would be to cut them open and mix their contents with the water.

glow sticks would give the same effect u just couldnt use a UV light u would need a normal LED that is white and it would still bring out the flourescent glow stick juice thats mixed in with the water

It may work, although Glowsticks only have a Life of about 8 hours Tops, so then after that, you're without the glowsticks, unless you change them every day. This would be rather time consuming, and expensive. LEDs can burn for 100,000 hours before dying, and would run farrr longer than 8 hours on 4.5v.

Would it be possible to just cover the opening of the jar with clear wrap or something similar and either tape it in place over the threads, or hot glue it to the rim.
