Who doesn't like lava lamps? And who doesn't like mixing chemicals? Nobody! So that's why everybody should try this super-cool mason jar chemical lava lamp. With no heat, its bubbly insides will amaze anyone - even your great-great-grandpa! No, seriously. So, in just 3 easy steps, make one of your own!

Step 1: Materials

For your own awesome mason jar lava lamp, you'll need the following:

  • (25 drops) food coloring (any color)
  • (1 Tbsp.) baking soda
  • (1 Tbsp.) citric acid
  • (1) mason jar (with no lid)
  • (2 cm) water
  • (8 cm) vegetable oil

Once you've got these, time for the fun part!

Step 2: Mix

Pour approximately 2 cm of water into the jar, and then pour 8 cm of vegetable oil in, too. They'll stay seperate, because water and oil are definitely not homie G's. Next, pour in all that nice food coloring and give it a bit of a stir!

Step 3: Fizzzz

Now, for the fun part! Add in the citric acid and baking soda. They'll almost immediately start fizzing because they only react in water. Sit back and enjoy this bubbly display! Place this somewhere, and it'll fizz for about an hour. If you do this, let me know! The first person to do it will receive a 3-Month Pro Membership. Pro memberships remaining: 1/1

Thanks for your time! Have fun experimenting with different amounts of citric acid and baking soda. This is super fun to do, and can by done by almost anyone! If you liked this Instructable, check out some of my others, and perhaps you'll enjoy some of them. Adios!

<p>have you considered putting Alka seltzer in it? I have seen that and this done before. Both work really well.</p>
<p>where do you get citric acid? can ont wwait to make this with my grandson thans for taking the time to posting this </p>
<p>Usually a grocery store, but sometimes they may not have it and you will have to go to a chemistry shop.</p>
<p>Would unsweetened lemonade mix work for the citric acid component? I've used that stuff as dishwashing detergent because the citric acid cleaned glasses really well with no water spot residue.</p>
<p>That should work if it's 50% pure citric acid or more. Just to be same, double the amount of lemonade mix but keep the amount of baking soda the same. Tell me how it goes if you do it!</p>
