We’ve been joining in with the 12 months of sensory dough series, and sharing a new type of dough each month. This month it’s fizzy dough, and we have cheated a little bit because our activity is not a fizzy dough but it is a really cool classic fizzy experiment that you can do using any type of playdough (shop bought or one of your favourite playdough recipes). If you haven’t tried this experiment before, give it a go!

Fizzy volcano activity with playdough. Explore the reaction between baking soda and vinegar to make an eruption with this fun fizzy dough activity

 

For this activity you will need:

  • Small bottle or jar
  • Playdough
  • Warm water
  • Bicarbonate of soda / baking powder
  • Washing up liquid
  • Food colouring (optional)
  • Vinegar

bicarbonate of soda and vinegar reaction experimentYour chemical reaction is going to happen inside the jar, so this will form the mouth of your errupting volcano. Use the playdough to build a volcano around it. You could get more detailed with this and create a whole dinosaur land including the volcano, with land, sea, and different terrains but we kept ours quite simple this time. Your playdough will get wet and covered in the fizzy volcano “lava” so if you have old playdough this is a good activity to get one more use out of it before it’s time to throw it out.

make a playdough volcanoInside the jar, put some warm water with a spoon of bicarbonate of soda. Then add some washing up liquid and some food colouring to give a better effect to the eruption.

Once everything is ready, add some vinegar to the top of your volcano and watch it errupt. If the vinegar isn’t having enough effect then stir it a little, or add some more

fizzy reaction between baking soda and vinegar science experiment with a playdough volcanoIt’s lots of fun to watch, and since the experiment is quite simple children can do all of it themselves. You could experiment with using different things to see which gets the better reaction – like replace the vinegar with lemon juice, and see what happens.

This experiment works because the bicarbonate of soda, or baking powder, is a base and the vinegar or lemon is an acid, and when they combine it causes this chemical reaction. You can read more explanations about the reaction here.
