I am constantly in search of experiments and activities which can improve the learning experience of school kids. In my childhood, I used to make telephone using a string and two paper cups at end, I hope everyone did it.
I made this little experiment a little more innovative by adding more receivers to it, i.e. now the message could be delivered to more than one person at the same time. I attached two extra strings to the main string between the two paper cups, at the end of each string I attached a paper cup. Hence a paper cup multi phone was ready. Students enjoyed a lot by talking to each other through this paper cup multi phone.
