DIY Lava Lamp, Erupting Volcano & MORE. Fun Science Experiments for Kids

Science Experiment - Lava Lamp etc

We had such a FUN afternoon with the kids doing some Science Experiments! We did a DIY Lava Lamp, an Erupting Volcano & the old ‘Inflate a Balloon with Vinegar & Baking Soda‘ trick. The kids had a ball (and so did we!). I highly recommend you do this with your kids, it’s educational, entertaining and loads of FUN! We did up a little ‘Movie’ of our Fun Science Afternoon and also steps on how to do these experiments yourself! We hope you enjoy!

So the first experiment we did was the:

You will need:

Two Empty Water Bottles or Jugs

Food Colouring

Vegetable Oil and

Alka Seltzer (found at the grocery store)

Now for the ‘how go’s’:

Fill each bottle a little more than half way with the oil (pic 2)

Fill the rest of the way up with water, leaving about 2cms at the top (pic 3)

Add 15 – 20 drops of food colouring (pic 4)

Then break the Alka Seltzer in four pieces (pic 5)

And (now for the fun part), drop each piece of the Alka Seltzer in one at a time and watch your Lava Lamp take shape!
