1. A teaspoonful of neutron star
They have a mass of about twice that of the sun (bigger than 10 suns) and are the smallest and dense stars known to exist in the universe.
2. Metals that explode when in contact with water
If we dig up one teaspoon of mass from a neutron star, the mass will weigh around 6 billion tons which proves how dense the star can be!
Here are a few lesser-known science facts that will excite and interest children and adults as they learn more about the subject:
Neutron stars are the remnants of giant stars that died in a fiery explosion known as a supernova. Neutron stars and their density are usually measured in solar masses.
There are certain metals like potassium, sodium, lithium, rubidium, and cesium that are reactive, and they tarnish instantly when exposed to air and explode when dropped in water!
The alkali metals have only one electron on their outer shell, making them ultra-keen to pass on this unwanted passenger to another element via bonding.
As a result, they form compounds with other elements so readily that they do not exist independently in nature. 3. Hawaii is moving closer to Alaska by 7.5cm every year
Yes! This is caused by tectonic plates which are in constant motion, driven by currents that rise and fall under them. Hawaii remains in the center of the Pacific plate and every year due to this constant motion, Hawaii is slowly and steadily heading to the North American platform, back to Alaska.
4. Sunflowers are known as hyperaccumulators Like many other hyperaccumulating plants, sunflowers remove metal compounds from deep in the soil and transport them into the stem, leaves and, flower head.
5. A cockroach can live for up to one week without its head Cockroaches are infamous for their tenacity and are often pointed to as the most possible nuclear war refugees.
Hyperaccumulating plants are used to clear up waste during a process called phytoremediation. They can take up high concentration of toxic materials and are adept at extracting radioactive metals from a particular place in a period of 3-4years.
