More Volcanoes

Volcano, Monday, 14th January, 2008
We can make a great volcano with bread soda and vinegar.
It works even better with wash up liquid. The lava flows for longer and more slowly.

This time we put vinegar in the bottle and the bread soda in the balloon. The balloon blows up when the bread soda falls in on top of the vinegar. This is because the gas given off from the experiment blows up the balloon.
