We were investigating the viscosity in an oobleck mixture and we found out that adding more cornflour made a higher viscosity than the rest of the mixtures.
We did 4 trials: To 1 cup of cornflour we added:
1) milk instead of water
2) salt added
3) soap added
4) added 1 more cup of cornflour
We found the trial with the added cornflour created the highest viscosity.
