2019:

Squeezing toothpaste onto a toothbrush

The inaugural PNCRC competition took place on Saturday, March 2nd, 2019 in the Córdova Recreational Sports Center in West Lafayette. Open to the public, this competition drew over 300 visitors and hosted four collegiate teams - two from Purdue, one from University of Illinois, and one from University of Texas.

Tasked with dispensing toothpaste on a toothbrush, each team designed contraptions around this goal with unique theming, of note was a fantasy setting and a rocket launch.

Competition Winners: Purdue Society of Professional Engineers
