What causes root beer to foam when creating a float?
You put the vanilla ice cream in the glass first and then pour the root beer into it. Then it begins to foam upwards. Do you think that the sugar in the ice cream causes this to happen?
Answers:
the cold ice cream causes the soda molecules to become closer together and squeeze out some of the CO2. The CO2 bubbles dont pop once they reach the surface because they are lined with fat from the ice cream
