Grinding solid colorless phenolphthalein indicator and solid colorless magnesium hydroxide base can produce a reaction that causes the mixture to turn pink.
How do Melissa & Doug’s “Water WOW!” Water Reveal coloring books work? Let's do some experiments to find out!
Adding dyes to salting out experiments can create a variety of interesting color effects as the dyes differentially dissolve in the aqueous and organic layers. Can this differential solubility of dyes be explained using intermolecular forces as a guide?
Polylactic acid (PLA) exhibits a glass transition from hard and brittle to soft and rubbery when immersed in boiling water. PLA-based structures containing a small metal object can be used as rattles when they are shaken. The sound of the rattles change when they are heated above or cooled below their glass transition, enabling them to be used as demonstrations.
Pharaoh's serpent is the name of a very interesting chemical reaction that produces a snake-like foam. Unfortunately, it requires the use of a toxic mercury compound. Explore this very similar reaction that can be achieved quite simply by using fuel tablets and calcium gluconate tablets and learn a lot about the chemistry that is involved!
What is some of the chemistry involved in the formation of ice clouds when boiling water is thrown into icy air?
Discover the secrets behind flame-shaped highlighter markings that not only disappear and reappear but also glow and flicker under the influence of acids, bases, and UV lights.
It has been claimed that because all water ultimately ends up in the water cycle, we drink water that the dinosaurs peed out. What does chemistry have to say about this assertion?
Tissue paper can be folded and cut with chemistry-related patterns to make decorative paper banners that can be used as Mexican-themed decorations. Chemistry concept connections include lattice energy, bandgap energy, and ionic crystal fracture.
The floating soap bubble is an impressive experiment that is surprisingly easy to carry out.
