My youngest and I thought we would make a little video today to show you some really simple science.
Here is a list of things you will need..
- Lemons
- Food Colouring
- Washing Up Liquid
- Bicarbonate of Soda (Baking Soda)
- Lollipop Sticks (not essential)
- A container/tray to stop the mess from going everywhere
After you have done these steps, you need to sprinkle the bicarbonate of soda and wait for the lemon to start foaming. To make the reaction better, use the other half of your lemon to squeeze more lemon juice over the top.
Keep prodding the lemon with your lollipop stick to release the colour and then continue to add bicarb and more lemon juice until you get a reaction that you are happy with.
The Sciency Stuff…
Lemon juice contains citric acid and when mixed with an alkaline (bicarbonate of soda) a chemical reaction happens. When the white powder (bicarb), and lemon juice join together, they make a colourless gas called CARBON DIOXIDE! The fizzing is the chemical reaction and the bubbles produced are CARBON DIOXIDE GAS!!!
(The washing up liquid helps make the reaction more fun but is also optional – we just loved the extra foam)
If your reaction isn’t what you expected, mash your lemon up a little more to produce more lemon juice, or squeeze more on using the other half of your lemon.
Thanks for reading, have fun!!!
