Monster Tea Party

Monster Tea Party

The girls wanted to have a tea party, so we used a bit of Science Sparks magic to make it more exciting.

What you need:

Baking soda ( bicarbonate of soda )

Baking powder

Vinegar

Washing up liquid

Water

Tea cups

Food colouring

Vinegar

Instructions

First I added some water to a bowl of baking soda and mixed it up with a bit of food colouring. This is what you can see in the little tea cups.

I then did the same with some baking powder to see what would happen. The baking powder is the lovely purple dough in the cake cases.

The sundae glasses contain, water, baking soda and washing up liquid.

We put some vinegar in a teapot and then I let the kids go wild.

If it doesn't work straight away give it a bit of stir.

Do be careful with the vinegar, it will hurt if it gets in eyes and DO NOT drink!

Did you find the baking powder worked as well as the baking soda?

The Science bit

Vinegar (an acid ) and bicarbonate of soda ( an alkali ) react together to neutralise each other. This reaction releases carbon dioxide, a gas which is the bubbles you see, these bubbles make the washing up liquid bubble up to give the reaction shown above.

Science Sparks was founded by Emma and Kerry who turned their passion for science and education into a wonderful resource full of fun and engaging science activities for children of all ages.
