Poke a small hole on the bottom of two styrofoam cups (make sure that the whole is in the center of the cups), thread a long string through the cups (be sure that the top of the cup is pointing out). Tie a knot at both ends of the string so that the cups will not fall off. When you are talking into the cup, keep the string tight so the person that is listening can hear.
two cups with a piece of string attached to them both.
Nothing, as it won't go anywhere. Only a taut string can transfer vibrations
thats all they had
Take two paper cups and poke wholes through the bottom. Get some string and insert it through the bottom of the cup. Tie knots on the ends of it so it will pull through the bottom of the cup. Then make the string taught and talk into the cup. If pulled taut enough, the string will carry the vibrations of your speech, and your string telephone should work.
I would say that plastic cups are better for string telephones because you cant get string through a metal cup.
Mainly because the two are utterly unrelated.
string and 2 cups
cups connected by string
yes it does work but it wont with threading string.
Punch holes in the bottom of two tin cans, string some string through it, tie knots at both ends, and there you have a fake telephone that doesn't work in any sense. =)
