Magnets and currents .

Brief Explanation: 

MAGNETS 

Magnets are obviously a material which has a powerful attraction.  In scientific way; it is a piece of iron (or an ore, alloy, or other material) that has its component atoms so ordered that it exhibits properties of magnetism.

CURRENTS 

A flow of electricity which results from the ordered directional movement of electrically charged particles.

In zero gravity, ping pong becomes real-life pong, because with no gravity to alter its course, the ball just keeps travelling straight in the same direction.

Fun Science Experiments

I remember when I was a child I had a book of fun science experiments. There were some experiments that I wanted to do and others that I did do. So, I feel like sharing some of them because everyone should do them some point in their lives. Be it they do it with friends, with their kids, siblings or whatnot. It’s fun and it’ll help to add to the good memories we already have.

1. Diet Coke and Mentos Eruption - One of the most popular experiments of modern times is the Diet Coke and Mentos Geyser. Made popular by Steve Spangler, this experiment is a lot of fun and sure to amaze your friends and family (assuming you do it outside rather than in the living room).

2. Invisible Ink with Lemon Juice - Making invisible ink is a lot of fun, you can pretend you are a secret agent as you keep all your secret codes and messages hidden from others. All you need is some basic household objects and the hidden power of lemon juice.

3. Make Your Own Rock Candy - Also known as Sugar Crystals and it’s my favorite experiment to do because it’s easy and tasty. They are made by crystallizing sugar and making it yourself means that you can make as many as you want, with any color and flavor you want.

4. Glow in the Dark - It’s always fun to make and see things glow in the dark. There’s actually a lot of experiments that deal with this, from making drinks that glow, glowing water, fake neon sign, glow in the dark alum crystals, glow in the dark crystal snowflakes, glow in the dark ink, glowing slime, glowing bubbles, glowing flower, and so on. 

5. Change the Color of a Flower - This is a very simple experiment and only requires a few things to make it possible. Water, food coloring, a cup (or vase) and a flower. It’s always fun to see a flower change into a different color that’s uncommon for it’s kind. Such as blue or purple roses, aqua magnolias, green carnations, etc. 

Putting a Grease Fire out with Water

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.

The Feminine Face of Space

You probably think this is a no brainer.

DUH people will swim faster in water, because syrup is thick. But the real answer is SUPER SURPRISING. 

Science put things to the test to this “simple” question. 

Sixteen volunteers took turns swimming in water and then a syrupy mixture.

Their times were thoroughly compared and, there was no difference between the speeds in the water versus the syrup. How can that be?

The explanation seems to lie in the fact that, while syrup does provide more resistance for the swimmers to overcome, it also helps them generate more forward momentum by pushing against the thicker liquid.

GOING “GREEN” IN THE ARCTIC

The growth of vegetation in Arctic climatic regions may begin to resemble that of more temperate and tropical regions. Researchers from NASA and Boston University conducted a 30-year study based firmly on satellite information to make this assertion.
