Science is fascinating and the reactions of certain substances can lead to some pretty mesmerising imagery! With the rise of social media there’s even more people showcasing their experiments and the wonderful effects they produce.
However, if you’re going to try any experiment yourself, make sure you know what you’re doing. Adding the wrong substance to another can lead to some very unintended results!
Below are 6 science gifs you won’t be able to look away from and explanations about what exactly is happening!
1) Dry Ice Bubble
Adding dry ice to warm water, immediately causes the dry ice to begin to bubble and create fog within its container. This effect is directly caused by the rapid warming of the dry ice. Dry ice is frozen, compressed carbon dioxide gas and when you add it to warm water, it combines with the water to create the fog (carbon dioxide and water vapor). Combining soap with this water creates a whole new effect. Instead of the dry ice just bubbling and forming a cloud, the soap traps the carbon dioxide and water vapor in a soapy bubble. As the bubble leaves its container and bursts, it releases the gases in a brilliant cascade of fog.
2) Milk Art
Milk has fat in it which allows the food colouring to float on top of it. This fat is connected with bonds holding the colour together. When you break this bond, it causes the fat to separate and causes the magnificent blending of colours and moving art.
3) Magnetic Liquid
A ferrofluid is a liquid that becomes strongly magnetized in the presence of a magnetic field. Ferrofluids are composed of nanoscale particles of magnetite, hematite or some other compound containing iron, and a liquid. The particles are suspended in a carrier fluid, usually an organic solvent or water, and clump together when in the presence of a magnetic object.
4) Dancing Oobleck
Obelisk is a Non-Newtonian substance, meaning that it has a variable rate of viscosity, acting as a fluid under some circumstances and a solid under other. It is a solution of cornstarch and water, which is a liquid under low-stress situations, but becomes more viscous when agitated, like when subjected to vibrations.
Fluorescein is a synthetic organic compound, widely used as a fluorescent tracer for many applications. The fluorescence of this molecule is very intense and it is actually the substance used to make highlighters. Adding this to water leads to spectacular explosions of colour as it dissolves.
6) Waterproof Sand
Hydrophobic Sand is sand coated with a hydrophobic compound. When added to water, this hydrophobic compound causes the grains of sand to adhere to one another and clump together, forming cylinders. When the sand is removed from water, it is completely dry and free flowing.
