How to make honeycomb science experiment - materials needed
1 How to make honeycomb science experiment - greasing the pan

Grease a baking tray with the butter or oil.

2 How to make honeycomb science experiment - sugar syrup boiling

“Bubbling sugar syrup”

Add 2 tablespoons of honey, 2 tablespoons of water and 3/4 cup of sugar to a saucepan. Cook the ingredients over a high heat without stirring to about 150oC. The sugar should melt, bubbles should form and the sugar should caramelize into a light brown or amber colour.

3 How to make honeycomb science experiment - honeycomb on tray close up

Remove the pan from heat and whisk 1.5 teaspoons of baking soda into the hot syrup. This will cause the mixture to foam up.

Stir just enough to mix the ingredients and then pour the mixture into the baking tray. Don’t spread the mixture as it will pop the formed bubbles.

Why Does This Happen?

The sodium bicarbonate reacts when you add it to the hot sugar syrup.
This is due to the heat of the solution breaking down the sodium bicarbonate into carbon dioxide, water and sodium carbonate. The actual chemical reaction is as follows:

2NaHCO3 > Na2CO3 + CO2 + H20

This type of reaction is known as a thermal decomposition reaction which means that the heat of the solution breaks the chemical bonds within the chemical compound. The bubbles from the carbon dioxide in the reaction caused the honeycomb mixture to rise.
