Saartje is a young mother of three children who seems to enjoy a crochet hook in her hands (and thread, of course). This Dutch is also a teacher and time He seems to have enough to judge from this experiment that has prepared his children.
With some empty bottles of soft drinks (or water), a string, a fastening point and a lot of ingenuity, Saartje's children learned some notions last year about the law of gravity, and they observed the capacity of the containers when filling, at the same time that (sure) they had a lot of fun and eased the heats of the summer - that although there will not be so extreme, surely no one despises a soak between May and September -. And I say last year, because the entrance is a bit old already, but surely for this summer has invented the odd novelty with which to entertain the little oness. And we are admired, because although in our relationship with the liquid element we have played with balloons, guns and even water sponges ... our experiments have not gone from demonstrating the change of properties on the surface of the water, or observing what happens when it freezes.
And if you want to emulate this ingenious mom, get down to work, you just need a wooden board a vertical surface to hold it, some tacos to which the bottles that we will place inclined to nail, and a rope not too thick to swing the upper bottle.
If we get that the top block is not very fixed we can move this bottle at discretion (vertically to fill it, horizontally to empty the contents). A few strategic holes in the rest of the bottles (inclined) will do the rest.
The water will slide looking for its final destination which can be a bucket, the doll's bathtub, or uncovered sprayers, to keep playing to get wet.
