Before you read this post, I have a confession to make. I have a school girl crush on Steve Spangler. He's so dreamy and he makes science fun. How can any person resist? *Sigh* Mind you, this isn't my first school girl crush. Back in grad school I thought my stats professor was super brainy and super dreamy too. *Double sigh*
Ok... moving on... Last week Baby Chuck and I made this lava lamp using directions from
Steve Spangler's super awesome website. Doesn't it look cool?
Here's what it looked like when put a flashlight behind the bottle::

Whoa- swirly sci-fi effects |
Want to make your own lava lamp? (Come on, I know you do!) If so, read on, fellow crapter!
Materials:
- empty bottle and cap (we used a soda bottle) <-- crap!
- vegetable oil
- water
- dark food coloring (we chose blue)
- alka-seltzer tablet (divided into smaller pieces)
- flashlight (optional- for alien effect)
Directions:
1. Fill your bottle 3/4 full with vegetable oil. Then, pour water into the bottle until it's almost full. Make sure to lave enough room at the top of the bottle for the alka-seltzer reaction, otherwise liquid will spill out.
2. Add 10 drops of food coloring. (Watch the water turn a different color as the oil remains the same.)
3. Drop your alka-seltzer pieces one by one into the bottle and watch the water bubble and fizzle.
4. (Optional: Put a flashlight behind the bottle and turn off the lights to see sci-fi alien effect)
5. Once you've dissolve all your alka-seltzer pieces, screw the cap on and tip the bottle back and forth. Watch the water and oil roll around. Feel relaxed.
