Meteors become meteorites when they hit the ground. Hundreds of meteors enter earths atmosphere every day, very few of them hit soil.

Watch: Glow-In-The-Dark Tricks You Need To Try

Materials: 1. Water 2. A clear plastic bottle 3. Vegetable oil 4. Food coloring 5. Alka- Seltzer Steps: 1. First, pour water into into the plastic bottle until it's one quarter full 2. Next, pour vegetable oil until the bottle is nearly full. 3. Then, wait until the oil and water have separated. 4. Next, add 12 drops of any food coloring of your choice into the bottle. 5. Then, watch as the food coloring falls through the oil and mixes with the water. 6. Finally, cut a Alka-Seltzer tablet into 6 smaller pieces and drop one of them into the bottle. Lesson: Oil and water do not mix, so the oil stays on top because it has lower density than water. The piece of Alka-Seltzer tablet releases carbon dioxide gas that rises and takes the colored water to the top. The gas escapes and, thus, the colored water falls down. Alka-Seltzer fizzes because it contains citric acid and baking soda, which are reactive with water creating sodium citric acid and carbon dioxide.

Materials: 1. A D size battery 2. Paper clips 3. 3 feet of thin coated copper wire 4. A 3 inch large iron nail Steps: 1. First, leave 8 inches of wire at one end and wrap most of the rest of the wire on the nail ( do not overlap the wires). 2. Next, leave 8 inches of wire at the other end of the nail. 3. Then, remove an inch of the plastic coating from both ends of the wire and attach one end of the wire to one end of the battery and the other wire to the other end of the battery. 4. Finally, put the nail near the paper clips and it should pick them up! Lesson: Magnets that cannot be turned off like ones on our refrigerators are called permanent magnets. Since the magnet we made can be turned off and on, it is known as an electromagnet. They run on electricity and are only magnetic when the electricity is flowing through the wires, which has the molecules in the nail attract to the metal paper clips.

One of the smoothest, most beautiful color changes I’ve ever seen.

The reaction is methoxymethyl deprotection of one of my agonists with concentrated HCl in acetonitrile as my solvent. The color change doesn’t happen in THF!

Today’s Illustrated Women in History is a written submission by James Purvis.

Caroline Herschel 1750 - 1848

Caroline Herschel was an astronomer and singer, and was the first woman to be paid for her contribution to science.

At the age of 22 Herschel, who had received training in music against the wishes of her mother, left her home in Hanover to join her brother William, who had established himself as an Organist in Bath, England. Herschel soon distinguished herself by becoming the principal singer in her brother’s Oratorio concerts, and received offers to perform across the country.

Alongside his musical career, William Herschel’s interest in astronomy grew, and with the assistance of Herschel he was eventually offered the position of court astronomer to King George III. At this time, Herschel chose to leave her singing career and become her brother’s scientific assistant, although some of her later writings suggest that this was perhaps not an easy decision.

Her skill as an astronomer was formidable, and in her obituary, the Royal Astronomical Society praised her ‘indefatigable zeal, diligence and singular accuracy of calculation’ as being significant contributors to her brother’s astronomical success. Herschel was awarded a salary by the court as an assistant astronomer, becoming the first woman to be paid as a scientist.

Her work included the grinding of mirrors for reflecting telescopes, taking observations of stretches of the sky, and detailing the precise timings and positions of the observed astronomical objects, as well as a great deal of calculation in order to translate these times and positions into usable data.

Between the assistance that she rendered to her brother’s work, Herschel found time for her own research, discovering a number of comets, as well as previously unobserved nebulae and star clusters, and compiling catalogues of the stars.

Herschel was awarded the Gold Medal of the Royal Astronomical Society, and was later made an honorary member. Today, she is commemorated by a crater on the moon which is named after her.

A magnet falling through a cylindrical hollow copper pipe. The magnets slows down in the center because as the metal falls it induces an emf in circular direction in the copper which in turn generates its own magnetic field under the action of Faraday’ law of electromagnetics but opposite in direction as determined by the Lenz’s law. This induces opposite magnetic field interacts with the magnet and tries to slow it down. Cool haa !!
