On Monday my class and I made these cool cup telephones.
Step 1, first you had to have a buddy, 2 cups, scissors and tape if you want, Step 2, you had to poke a hole at the bottom of boths cups then get a string that is almost 3 metres and put it through the holes of the 2 cups.
Step 3, you had to tie the ends of the strings so the string wouldn’t come off so easily, then you and your buddy have to take one cup each and step back so the string would be taut or else the string would be slack and won’t work.
Then one person of the both of you have to talk in the cup and one person has to put the cup in their ear so they can hear the other person.
If you make one, you should use a plastic string instead of wool because you won’t hear the person clearly if you use wool for your string.
