I teamed with Xiaofeng Lin in this thermochromic ink experiment.
We decided to test out with different ingredients in these little squares. Ingredients are marked aside.
We then heated it up and found out only Blue left, and whichever square without Blue in it disappeared.
We sewed conductive thread in each of the square and wanted to know if the circuit can bear this length of resistance.
It turned out only two rows of conductive thread worked, and three rows failed. The squares in the second row that didn’t work quite well may be too thick when we painted.
We measured the resistance of three rows and calculated how many resistance this circuit can bear to heat up.
