Creepy Glowing jars of parts is fast and easy!
Jars any size shape etc.
Fake body parts, I have fingers, eye balls, brain and heart
water and scissors
1st: Remove the ink cartridge from the highlighters
2nd: Cut them in half (helps them leak faster) and put them in each jar, larger jars may need 2 highlighters. I combined a yellow and blue to make green in a couple...
Fill about 2/3 of the way up with water, leaving room for adding body parts later. You can see the ink start to drain almost instantly.
After about 5 min they look like this... I let them soak an hour or two, overnight if time allows.
The highlighter ink makes the water glow in a UV or blacklight.
