not disturb! And green means: Communication allowed. At the

same time, this experiment is also an electronic game.

Every switch can turn off the base current of its associated tran-

sistor, whereby also the connected LED goes off. Normally you

would press only one button or one after the other. However, if

you press both buttons at the same time, both LEDs will go dark.

But when you release the buttons, only one LED will go on, and

no one can foretell which is the one that turns on. It is almost

impossible to release the switches at the very same time. One

switch will open sooner than the other, even if the difference is

just a micro-second, and turns on the LED at the side.

Here is how the game works for three people: Two will each

press a switch, the third one will give the command to let go.

Now you will see who reacted faster because only this LED

will turn on. You can take turns and the winner could be es-

tablished after several rounds.
