How will you check slime?
We thought very rigorously about check our slimes, and devised three checks.
The Stretch Check
This concerned attempting to stretch the slime between our fingers.
Winner – Fybogel Slime
Keep in mind to make use of the identical quantity of every slime.
The Viscosity Check
We arrange a viscosity race to research which slime was essentially the most viscous. Viscous liquids are thick and move extra slowly than much less viscous liquids.
Winner – Cornflour Slime
Keep in mind to make use of the identical quantity of every slime and time how lengthy every takes to move between the identical two factors.
