Make-your-own "Lava" Lamp

I'm embarrassed to even admit how much time I've spent on Pinterest this summer.  I always plan on just looking for a few cool ideas after the kids go to bed, but the next thing I know, it's 2 a.m. and my mind is spinning with all my new "pins" and the fun I'll have with them.  The downside is that the kids have to deal with a tired mommy the next day, but the upside is that I find cool ideas like THIS Lava Lamp.

As soon as I saw it, I knew it would make it onto our Summer must do list.  I suspected my kids would get a kick out of it and they did!


Here's how we did it:

1.  Gather your supplies ~ cooking oil, water, food coloring, an empty water bottle, and Alka Seltzer antacid tablets.

Oops, the Alka Seltzer tablets didn't make it in the picture.


2.  Fill your bottle about two thirds of the way with oil then fill the rest with water, leaving about an inch free at the top.

Partially filled with oil




It was fun adding the water and watching the layers separate.
** NOTE ** We liked watching the water layer "sink" to the bottom, but we had to wait awhile for the bubbles to disappear for the next step.  Adding the water first, then the food coloring and finally the oil, wasn't quite as fun, but it was a bit faster.

3.  Add several drops of food coloring.  (If you did the oil first, then the water, it'll take a little while for the drops of food coloring to "break through" and tint the water.)

Mommy adds the food coloring.
4.  Take an Alka Seltzer tablet and break it into 3 or 4 pieces.  Then drop a piece in and watch the magic. 

The kids are looking annoyed that I made them stop for a picture first!

5.  As soon as the tablet hits the layer of water, it will start to fizz and the colored water will erupt!




4.  The bubbles will stop as soon as the tablet dissipates, but it will start up again as soon as you add another tablet.  If the oil layer starts to become cloudy with tiny bubbles, just let it settle for awhile and then you can do some more.

My kids loved it so much they worked really hard to be good so they could "earn" more antacid tablets to do it over and over again.

  23. Do you have to leave the lid off the bottle?

    ReplyDelete
  24. You don't have to leave the lid off. We did just because the bubbles start almost immediately and the kids didn't want to wait for me to screw the lid on first. However, if you're worried about it spilling, you can put the lid on. There will be some carbonation from the tablets, so if the lid is closed, expect a little release of the gases when you reopen the bottle (similar to opening a bottle of soda) but I don't think the pressure would build up too much unless you put in several tablets at once and keep the lid on. Hope that helps.

  27. I've just had a great day with my seven-year-old grandson - his reaction to this was "WOW!" and when mum and sister came to collect him their reaction was the same! Great fun and we could screw the top back on and he it took it home to show dad too. Ten out of ten for this.

  28. I didn't have antacid so I used clear vinegar instead of water and added baking soda with similar results.

  29. Definitely doing this with my son :) Do you recommend new water and oil each time, or can you cap and store for awhile?

    ReplyDelete
    Replies
    1. You can definitely cap and store for awhile. We've kept them for months before. Plus, if it's tightly capped, it's fun to just tilt the bottle and watch the contents slosh around.

  30. thank you now i know what to do

  31. is it something that the kids can take home with them ?

    ReplyDelete
    Replies
    1. Yes definitely. Just wait for it to stop "erupting " then put the lid back on it. You can give them directions to use more alka seltzer tablets or it's fun just to move it back and forth and watch the waves of oil and water.

  32. HI, I cant find alka seltzer anywhere. any ideas for a substitute? party is thurs and with out thinkng already told my 5 year old that we are making lava lamps....

    ReplyDelete
    Replies
    1. Oh no. I'm really not sure of another substitute. Have you checked the pharmacy department of your local store? If not, it's still pretty neat to just have the colored water and the oil. It doesn't erupt, but it's fun to shake, then watch the two separate again.

    2. Just use salt! I did this with my middle school science class & we simply sprinkled salt on top. We did ours in a jar instead of a bottle, so the salt was easier to sprinkle on top. Once the salt hits the oil layer it will start to react & cause a similar effect.

  33. Awesome does it last long?

    ReplyDelete

    1. The bubbling effect just lasts for about a minute (depending on the size of the tablet you put in), but the actual liquid in the bottle can last for a really long time!

  35. I just made this with my 8 year old son. It was much cooler than I expected. He really enjoyed it and wanted to share with the whole family.

  36. can we use any antacid as a substitute of alka seltzer in this lava lamp

    ReplyDelete
    Replies
    1. We tried this with regular antacids and it didn't work. We also tried salt, and it kind of worked but wasn't especially impressive.

  37. Can you use plastic bottles or does it have to be glass?

    ReplyDelete
    Replies
    1. You can definitely use plastic, Janet. Our bottles were plastic and I'd recommend it in case the kids drop it or knock it over. Just try to find a bottle with smooth sides if you can, it makes it easier to see the bubbles inside. (Ours were VIOS water bottles)
