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

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:

DIY Lava Lamp

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!

Keep adding the Alka Seltzers to watch the fun over and over again!

The next experiment on the agenda was:

The Erupting Volcano!

For this you will need:

Four Plastic Cups (or two cups per child)

Vinegar

Bi-Carb Soda and

Red Food Colouring

Fill two of the cups with 1/4 cup of Bi-Carb Soda

Fill the other two cups with 1/4 cup of Vinegar Each

Add 6-7 drops of the Red Food Colouring to each cup

Now pour the cup of Vinegar into the cup of Bi-Carb Soda mixture and watch your Volcano ERUPT!

Then for our third and final experiment of the day we:

Inflating a Balloon with Vinegar & Baking Soda

For this experiment, all you need is:

A Balloon for each child

A Water Bottle each

A Small Funnel

A Large Glass Jar

Baking Soda (about 1/2 cup) &

Vinegar

Half fill the water bottles with Vinegar and set aside

Then the children add the Bi-Carb Soda to the balloon using the funnel (attach the balloon to the funnel then place in a glass jar first – this make is SO much easier!)

Attach the balloon to the water bottle so that the balloon hangs over one side.

Then tip the ballon upright and watch as the balloon MAGICALLY INFLATES!
