One more idea for the tricky, one fun craft that involves making a teaphone Besides being an artistic work that puts psychomotor skills into operation, it is also a simple scientific experiment that will bring children closer to sound waves and their transmission.
We will need a couple of empty yogurt cups or a couple of used toilet paper rolls. If we choose the second option, which is what we have done, we will also need cardboard and glue, to make some circles and glue them at one end so that there are no gaps in the joints.
Once painted with acrylics we will make a small hole in the base of our cylinders and pass through them a string, preferably of organic fiber, such as esparto. It is necessary to make the hole of the exact size so that the string passes without leaving gaps. The rope, our transmission cable, will be tied with a knot inside the cylinder.
Then the fun begins, because when speaking through one of the cylinders we will realize that the sound reaches the receiver quite clearly and will be an amazing experience for the child.
This proposal of Fun and scientific craft of making a phone It can also give us the opportunity to do other simple experiments on the properties of sound or waves, which are sure to fascinate children, and that I will propose in successive subjects.
