Unconventional switch - Team 4

 Unconventional switch - Team 4 

 

    For our unconventional switch, we chose to use Gatorade as the method for turning the circuit on and off. Using a power supply, two 100ohm resistors, A red LED, and two alligator clips, we connected the components together and placed both clips at the top of a cup without letting them touch

    Gatorade contains a high amount of salt, which lets the current pass through it and complete the circuit. When the liquid reaches the clips, the circuit is completed and the LED turns on. 

    The practical use for this setup is as an indicator to show when to stop pouring your drink. Like if it was dark at night the led would let you know. This could also be improved, if we used a speaker it would make an even better indicator for the visually impaired. Alternatively you could reverse this, with the led on when the cup is full. You can check if anyone stole some of your drink because the led would turn off if the liquid went lower
