Fizzy experiment

Fizzy experiment

Science experiments are so much fun for kids and so easy to do in your own home. This simple fizzy experiment will intrigue the kids and have them asking why and how?

What you need:

  • big candle
  • tall glass
  • birthday candle
  • baking powder
  • matches
  • spoon
  • vinegar

Number of players:


Light the big candle and drip some wax into the bottom of the tall glass.

Stick the birthday cake candle in the wax so it stands upright in the glass.

The glass must be taller than the candle.

Add spoonfuls of baking powder to the jar, keeping away from the flame.

Pour in some vinegar so that the powder fizzes.

After some time the candle flame will extinguish. Why? Mixing baking powder and vinegar makes carbon dioxide.

Unlike oxygen gas, the flame doesn’t easily burn carbon dioxide.
