M&Ms in the water: Science with creativity

Chocolate M&Ms are covered by a layer of sugar and food colouring. When put into the water, the sugar gradually melts taking with it a certain amount of colouring which, in its turn, is also soluble in water. The sugar flows in the water from areas with a high concentration of sugar to areas with a lower concentration. At some point, the colours do not not mix anymore! A possible explanation is that in the border area between then, the sugar concentration is almost the same, diminishing the tendency of both the sugar and colouring flux.

Giant soap bubbles

Making soap bubbles makes any outdoor activity much funnier – specially if there is a smooth breeze to take them to the sky. The size of both the soap bubbles or the huge tubes depends on the used materials as well on the students’ expertise. The soap bubbles have no colour, but their amazing structure and the light properties make visible a complete rainbow. The outer surface that keeps the air inside is a thin water sheet isolated between two thin layers of soap molecules. It’s the way the light interacts with these layers that creates the colours we can see.

Experiment on compressibility and air expandability

Air is a gas and as such has the property of expanding, increasing its temperature, that is to say, increasing its volume and on the contrary, when this gas decreases its temperature, it tends to contract and with it to decrease its volume.

Synthesis of Fluorescent Quantum Dots

The visible absorption and photoluminescence of CdSe nanoparticles depend on the size of the particle. A sudden injection of room temperature selenium solution into hot cadmium solution produces quickly-growing seed crystals. Samples are withdrawn from the hot solution and quenched at room temperature to produce a series of increasing particle sizes and observable change in color.
