Bluebirds discussed the meaning of mixtures (solutions) today and found out how they will move and fill any spaces. We talked about filling a jar with marbles, sand and water. Kai explained Why cornflakes don’t disappear in milk and neither does the sugar… but it dissolves.
Outside, Bluebirds were really excited to watch the coke and mentos experiment!
When Mrs Johnson released the Mentos mints into the bottle, the sugar free Coke erupted out of the bottle and shot high into the air. The Mentos contain gelatine and gum Arabic which reacted with the Coke, separating the carbon dioxide gas from it.
