To make our volcanoes erupt we used baking soda and vinegar.To make the cone of our volcano we made dough using flour,water and green food colouring and covered a bottle with it.
When our volcano was ready we poured hot water and red food colouring into the bottle;then we added lots of baking soda and the vinegar.I didn't think it would work because anytime I try make a volcano at home it doesn't;but it did.
After we had cleaned up(which took a while because flour was everywhere) we made posters describing the reaction between the acid(the vinegar) and the base(the baking soda).It was a great science class and I can't wait until next week to see what experiment we do!
