Playing with the vacuum is just not something the boys have thought about doing before. That might be because I love that vacuum dearly and have told them that it is probably the most expensive thing I own. They had alot of fun and were able to make crazy sounds come out of it!
One of the sounds was a high-pitched humming sound and the other was a terribly annoying buzzing. Then the broke out the shop vac to test out Mr. Bernoulli's Principle.
