Science Fun – Dancing Sultanas
What will happen if we placed sultanas into a glass of soda water? Watch and be amazed!!!
Dancing Sultanas is a super easy and fun science experiment for kids! It is so simple to set up and only requires basic materials.
What you will need?
You will need a glass of soda water (sparkling fizzy water), about five sultanas and food colouring is optional.
We poured some soda water into a small glass bottle and dropped the sultanas into the fizzy liquid. The colouring is optional.
The soda in the water creates the fizz and bubbles. Soon the bubbles start to pick up the sultanas and carry them to the top of the glass. As the bubbles pop at the top of the liquid, the sultanas go back to the bottom of the glass and the pattern repeats again.
We also placed some sultanas into a glass of plain tap water to see what would happen. They just sank straight to the bottom of the glass. My kids did noticed that there we some small bubbles on the sultanas but not enough to make them dance, float to the top of the glass.
