Bat Brew Lava Lamp
Supplies:
- Clear plastic bottle or glass jar
- 2/3 cup vegetable oil
- 1/3 cup water
- Food coloring (green, purple, or orange for spooky potion)
- Alka-Seltzer tablets (for fizzing bubbles)
- Tiny plastic bats or bat confetti (lightweight to float inside)
- Optional: glow sticks or small LED lights for glowing effect
Directions:
1. Fill the bottle 2/3 with vegetable oil.
2. Add water until nearly full, leaving some space at the top.
3. Add a few drops of food coloring – it will sink into the water layer.
4. Drop in tiny bats or bat confetti to float in the potion.
5. Break an Alka-Seltzer tablet into chunks and add a piece to the bottle.
6. Watch as bubbles form, blobs rise and fall, and bats swirl around in your bat brew lava lamp.
7. Place a glow stick or LED light under the bottle for an eerie glowing effect.
