AMAZING WATER TRICKS YOU SHOULD TRY AT HOME|WATER EXPERIMENT
1)Hot water and pencil:At the negative pencil tip (cathode),positively charged hydrogen ions (protons)meet and form hydrogen(H)that bubbles to the surface.
2)Upside down glass of water:During this experiment, when you flip the water glass over, the water in the glass is pulled down by gravity. However, the force of the water pushing down is lower than that of the force of atmospheric pressure, which is pushing up on the card. Due to this, the water stays in the glass only
3) Dancing rice (water,baking soda, food color, rice & vinegar) :-The combination of rice and carbon dioxide gas is less dense than the rice alone,so when many "bubbles" form on the rice, they lift the rice to the surface.when some of the bubbles break, the density increase, the rice sink and then the whole process is repeated. This makes the rice appear to dance.
4)upside down water bottle trick (toothpick): Between the air pushing on the liquid and the water molecules sticking together, the water will not fall out of the bottom of the straw
saftypin & water : a pin is much denser than water, and it should sink
Magic leak proof bag :Think of polymers as long chains of beads.when you stab a pencil through the bag,the polymers move apart.Because polymers are flexible.When you stab a pencil through the bag, the polymers push back toward the pencil and form a temporary seal. This prevents the water form leaking out of the holes
Drops on Coin : As drops of water are added onto a penny, the adhesive force between the water and the penny keeps the water from falling off
water and toothpicks : This process is called capillary action. The result is that the water travels to the tips of the broken toothpicks. As the wood absorbs more of the water, the bent wood fibres expand and straighten out. Each toothpick end pushes against the others.
Oil and Water : The oil floats on top of the water because it is less dense or lighter than water. The food coloring has the same density as the water so it sink through the oil and mixes with the water. When you add the tablet it sinks to the bottom then starts to dissolve
