Wow what fun!
We had our container of bicarb, and each helped pour a little vinegar in until it exploded.
Once we saw what happened we thought it would be a fantastic idea to place our tray in the sandpit and build the sand up and around to create our mountain for the volcano.
Once again we poured some vinegar again and it erupted over the sand. We shrieked with excitement and wanted to continue it over and over again.
