Here are some cool tricks that you could do for your kids, giving them a taste of real-life technology and spark the innovative imagination. These experiments have probably been seen by most people but some are not. This is for entertainment purposes only and earthkin is not responsible for any damaged property, persons or loss etc… Give them a try and let us know what you think!
Demonstrate lightning – or electricity in the air. A balloon rubbed against hair creates static electricity the same way that clouds against the earth create lightning. This is the essence of lightning rods.
Coke and mentos – put a full pack into a 2 liter of coke and watch it explode!
Put food coloring in different vases, then to each, add a white carnation and watch them change color.
Roll a few paper towels up then put one part in each cup filled with your choice of food coloring.
Vinegar dissolves the shell of an egg, after it’s dissolved you can push it into the opening of a small bottle, defying physics!
[needs no description]
Fill the bottom of a plate with milk. Drop several colors of food coloring in the center then put a q-tip with some dish soap right in the middle and watch the magic happen.
Cut open a diaper (pampers etc) and rip the “stuffing” apart then put it all into a ziplock bag and shake it until you see a small collective of polymer powder at the bottom. This powder will turn an entire glass of water into gel, and will keep the water in the glass when turned up-side-down. Then for extra credit, add some salt to the gel and watch it turn back into water.
Similar to other carnation tricks, split the stem of just one flower and put each into a different colored water.
