Baking Soda + Vinegar Volcano

A classic fizzy eruption — the science experiment every kid remembers.

Steps

1. Build or use a small container as the “volcano,” set on a tray to catch overflow.
2. Add a few spoonfuls of baking soda inside.
3. Mix vinegar with a few drops of red food coloring, then let your preschooler pour it in.
4. Watch the “lava” fizz and erupt — refill and repeat as many times as they want.

Notes

This is easily repeatable — just rinse, reload with baking soda, and go again.
