These days, the latest thing for disposable
soap dispensers is "
foaming soap." It's actually a pretty good idea (especially when kids are using them) as the dispenser has a built in foaming thing (ok, don't ask me what it's actually called) that adds air to the soap as it comes out and makes it all frothy. It means that you end up using less soap than you might have needed otherwise. Excellent.
I wondered, if we put paint into the empty foaming soap dispensers, would the paint also froth up going through the frothy part? We had to experiment! Combining
art and
science is a lot of fun.
Through some trial and error, we discovered that you did still need a soapy solution with the paint in order to get it to froth well. We found that different quantities of soap/paint/water gave different types of foam. We used this activity to
experiment, explore density and viscosity, talk about
colours, colour mixing, develop hand muscle strength, use our
senses, do
printing, make pictures, work on
oral language and vocabulary, etc.
