You said we would never use the book.

I have now proven you wrong, Michael. 

Bwahahahaha.

Anyway.

It was Sunday midnight. I was tired. My cold had begun to creep in.

In the midst of the turmoil and exhaustion, I went to the IM lab with one mission – to finish my homework.

And so I did.

I retraced the steps taken in class. I made the simple circuit with an LED and a resistor. And then it was time to think of the ideas.

I thought of a few ideas before: simply asking someone else to press the switch (that wouldn’t fly), filling up a cup with salty water and putting in electrodes to complete the switch (too mainstream), putting an aluminium plate on two people and have them hug to complete the switch (my friend mocked me for this idea and then I couldn’t even find the aluminium sheets I needed in an empty midnight IM lab, so I guess this wasn’t it), until I settled for the book switch. 

I then tested the wire tape. It worked.

I then cut it and tried connecting it by making the two wire tape pieces touch. It worked.

Then I stuck them to the book. It worked. I even did it without my hands.

Success.
