Today I will tell how to conduct a simple, but very interesting and entertaining experiment, which can be shown to children. I am sure that any child will be delighted with such an event. Besides, this is nNot only interesting, but also informative, and most importantly, very easy and safe. My grandchildren really appreciated this idea!
All we need is a glass of water and a bag of ground cinnamon. The glass must be transparent, otherwise the child will not see anything. Pour clean water into a glass to the top, then pour cinnamon in a thick layer, approximately as shown in the photo.
It is already getting interesting, since a thick layer of cinnamon not only does not sink in water, but does not even start to get wet. Then the experiment itself begins, dip your finger in the glass with water or invite your child to do it. Through the glass you can see how the finger could not break the layer of seasoning, and the cinnamon envelops it tightly. But the most interesting is yet to come.
Now get your finger out. Look at him - it remained completely dry, it will only have a thin layer of cinnamon. There will be no limit to the surprise of children and they will immediately want to repeat the experiment. Do not forget to explain to your child that cinnamon is made from the inner bark of a tree, and a tree has a much lower density than water, so it does not sink. And due to the fact that it is a loose finger cannot "pierce" its layer. Simple and very interesting! If you liked this idea for an experiment - like and subscribe to the channel!
