Bobbing for apples is an absolute classic at Halloween but why not try something different this year and make yourself an Apple Eruption instead.
STEP1 - The first thing is to make our apple volcano and we’ll need to have an adult help out. Get an adult to carefully carve out a hole in the top of your apple.
STEP2 - Fill about half of the hole you just made with 3 teaspoons of baking powder.
STEP3 - Place your apple on a plate or somewhere that you don’t mind making a mess.
STEP4 - Mix a few drops of green food colouring into your white vinegar to make things even more disgusting.
STEP5 - Let’s start our Apple Eruption! Fill the rest of the hole in the top of your apple with green vinegar...
STEP6 - Sit back and relax and enjoy your Apple Eruption.
Hope you enjoyed your Apple Eruption but what’s going on?
This is a Halloween twist on the classic volcano experiment. It’s the age-old ‘acid/base’ reaction.
Our white vinegar is our acid and the baking powder is our ‘base’ (otherwise known as an alkali).
When the acid and the base mix together we get a chemical reaction. We can tell there’s a chemical reaction going on because of all the bubbles we can see within our ‘green lava’ as it flows over our apple. These bubbles are full of carbon dioxide.
