Clean rust using Coke

Materials
1. Rusty material.
2. Coco cola.
3. Sandpaper.
4. A clean cloth.

How Do I Do It
1. Take the rusty metal and pour coke on it.
2. Rub it with a sandpaper and rub it with a clean dry cloth .
3. Keep repeating this until the rust is totally removed.

Reason
Coco cola contains acid which reacts with the the rust to form salt and water. When we wipe we remove the salt as well as the water therefore giving it a bright and clean look.

Clean your pennies using some things in your home

Materials

  • 20 dull and dirty pennies
  • ¼ cup white vinegar
  • 1 teaspoon salt
  • A clear shallow bowl (not metal)
  • Paper towels
  • Spoon

How Do I Do It

  1. Put the salt and vinegar into the bowl and stir until it dissolves.
  2. Put the pennies into the bowl for about 5 minutes. Watch them when they first go in. What do you see?
  3. Take half the pennies out and place them on a paper towel.
  4. Take the second half out and rinse them off very well. Place them on a paper towel and mark it as being “rinsed”.
  5. Wait about an hour and then check back on your two piles. What differences are there between the two? Record the differences and make some guesses about why they are different. The rinsed pennies will be bright and new looking.
Reason
When the vinegar and salt dissolve the copper oxide they make it easier for the copper atoms to join with the oxygen in the air and the chlorine in the salt. When the pennies are not rinsed it allows the chemical reaction to occur. This makes up a compound called malachite which is what coats the dark pennies.

Lip balm using bees wax

Materials
  • 2 tbsp coconut oil
  • 1 tbsp of beeswax
  • ½ tsp honey
  • ¼ tsp baking soda
  • Several clean tin lids, or small tin or glass jars
  • 1 microwave-safe bowl
  • 1 fork or whisk
  • Wax paper
  • Saran wrap or aluminum foil
  • Essential oils (optional)
How do I do it
  1. Place the beeswax and coconut oil in a microwave-safe bowl. You should use less beeswax for a softer lip balm or the entire tablespoon for a firm lip balm.
  2. Cover the bowl with a piece of wax paper and heat the beeswax and coconut oil in the microwave for 3 minutes, checking it every 30 seconds to make sure it doesn't overheat.
  3. After the mixture is melted, take it out of the microwave, being careful not to spill it or burn yourself.
  4. Add the baking soda, honey, and essential oil to the mixture. Whisk together, using the fork, for at least a minute.
  5. After the mixture appears consistent throughout, pour it equally among the tin lids or jars.
  6. Carefully place the containers into the refrigerator; let it cool. If you do not have access to a refrigerator, set the tin lids aside in a cool area to give it a chance to harden.
  7. Place a piece of plastic wrap over each tin of lip balm to keep dust out and moisture in. If using small jars, simply close them up with their accompanying lids.

How to make a rocket

Materials required
1. A Bottle
2. A Cork that will fit the bottle tightly
3. A Cardboard piece
4. Baking Soda
5. Water
6. Lime juice

How Do I Do It
1. Take the bottle and half fill it with water
2. Pour lemon juice and mix it with water
3. Put baking soda into the bottle and fix the cork on it tightly
4. Shake the bottle well and keep it down
5. Go back a few feet and see what happens

What Will Happen And Why
1. The cork will shoot through the air with a big blast and will fall down
2. This happens because the baking soda reacts with lemon juice which is an acid and produce carbon dioxide water and salt
3. The carbon dioxide makes the cork blast out and fly

Quiz your brain

Q 1. Why does paper burn when kept on top of a candle flame whereas a paper cup containing water does not burn or catch fire?

Q 2. Why does a glass filled with water to the brim and covered by a piece of paper, cardboard or handkerchief does not spill water when overturned but a glass half filled with water empties and falls down when overturned?

Q 3.Why are load stones attached to the railway electric lines?

Q 4. Why does a bird which sits on a live wire does not get electrocuted?

Q 5. Why does the water in an earthen pot cooler than the water in a metal pot?
                                                                                                                                                          
Ans 1. When the paper cup is filled with water, the water absorbs the heat from the candle flame and does not give paper the optimum temperature to burn or catch fire.

Ans 2. The pressure on both sides are equal.

Ans 3. When heat is given to a metal it expands and when the metal is cooled it contracts. Similarly during summers due to the heat of the sun the electric wires would expand and this might lead to short circuit. For the same reason load stone is attached to the wires to prevent chances of a possible short circuit.

Ans 4. The bird sitting on the wire does not get electrocuted because the circuit is not complete.

Ans 5. There are very small pores in the walls of the earthen pot and water fills these pores and absorb heat from the water inside the pot to evaporate. This does not happen in the metal pots because there are no pores.
