In Room 2 we made a prank hand shake. The prank handshake was a creation to prank people with a shake.  We made it with a battery connected to the power switch.  Next we put the wire on to make the prank handshake.  Then we put a button switch so when someone shook my hand they will press the button switch and it will make noises.   Lastly we put a buzzer to make the noises. We used rubber bands to put the prank hand shake on our hand and arms and we asked people to shake our hands.  This is the picture of the prank handshake.
