Non-Newtonian fluids are a special kind of liquid that can sometimes act like a liquid, and sometimes act like a solid. Students in Chemistry Club learned about this concept, and about the term 'viscosity', by creating their own slime out of PVA glue, bicarbonate of soda, shaving foam, and eye drops.
The students experimented with varying the quantities of the ingredients, to examine and compare the properties of the resulting slime, and finished by considering the type of marketable product their work could relate to.
Unsurprisingly, the students had a lot of fun producing and examining their very own batches of colourful slime. This adds to their list of recent Chemistry creations, which also includes bath bombs, hand warmers, and lava lamps.
