Wait a minute... you're not a lava lamp. This article got my hopes up and dashed them with one fell swoop. Curse your deceptive title!

I heard you can replace alka seltzer tablets with salt. I know this is true but which one is better to use? I really need my answer fast because I have a science fair project coming up. Thank you!

how can i make it last more longer? and can alka seltzer be replaced by any thing else?

Would baking soda and vinegar last longer than alka seltzer?
I think it would

If someone combined this Instructable with this one :!/

then you've got yourself a lava lamp. ;D

a strong light bulb might give off enough heat so that it bubbles, like a real lava lamp.

if it doesn't it'll still look better being lit up instead of just in a bottle. ;D

don't hope on it too much guys...the way i see's a one time lava lamp.when all Alka-Seltzers are dissolved.there won't be any movement anymore.real lava lamps make use of the heat from the lamp to move those blobs around.

Err, I've been trying to make lava lamps for years and have never been successful. PLEASE add more pictures/ more detailed instructions.... and a video of it in action.

Please finish this instructable! It's a good idea, but the description of the process is overly vague and it desperately needs photos/illiustrations.
Ditto. Also a movie would be greatly appreciated.

This obviously looks like a good project, but the instructable, sadly, is not very in depth. I know it has potential, so please add some more pictures and better instructions and republish please. =]
