This is the first experiment in the "Work of Air" section of the geography album. It is supposed to show that air takes up space. When you pour the water quickly from the tumbler into the funnel that is sealed to a bottle with plasticine most of the water should remain in the funnel. I tried this at least fifty times. Fifty shades of failure. I tried several different bottles. I also tried a different funnel. The directions said that the funnel end should be a straight-across end rather than angled. I didn't fail any harder with the angled funnel than I did with the straight funnel. I also tried several types of clay. I occasionally got the water to go in a little more slowly and bubble a bit, but never stay in the funnel.
You can read more about this experiment over at Frugal Fun for Boys. Sarah is apparently a little handier than I am.
I couldn't find any videos of this working. My suspicious mind says, "That is because no one can get it to work."
Oh. And one of the boys took a drink out of the glass before I took my pictures. So, now there is a dirty lip print on the drinking glass. Even the photo is a "fail."
