As fundamental forces go, gravity is pretty weak. It can easily be overcome by air pressure, as this classic demo shows.

How To Make A Rocket For Less Than A Dollar

You can use sugar and kitty litter to make a rocket that shoots up over 2,300 feet (700 meters). And it cost less than $0.50 to make. Learn how: http://bit.ly/1G0hn8O

We grew some cress in box with a lid on it, that had one small hole for light. The result: a beautiful example of phototropism, plants growing and moving towards a source of light.

This is a great activity to try at home with the kids.

“Adding colour to water… in zero g” [x]

A red hot ball of Nickel placed on a block of ice.

Materials: 1. 3 white carnations 2. Scissors 3. Food coloring 4. 3 small cups 5. Water Steps: 1. First, get the 3 small cups and add 3/4 of the cup with water. 2. Next, in each cup at 8 drops of food coloring of your choice. (Make sure to pour different colors for in each cup to create more multi colorful flowers) 3. Then, snip the last centimeter of the carnations' stem and place each flower in the colored water. 4. Finally, wait for 2-4 days to see the results. Lesson: Transpiration is when plants draw water up through its stem, and , thus, the water evaporates from the leaves' stomata. As the water evaporates, it creates pressure that brings more water into the plant. Since the water had color, it made the flowers become that color.

Materials: 1. Half a lemon 2. Water 3. Spoon 4. Bowl 5. Cotton Bud 6. White Paper 7. Lamp Steps: 1. First, squeeze the lemon juice into the bowl and add 6 drops of water. 2. Next, mix the water and lemon juice with the spoon. 3. Then, dip the cotton bud into the bowl and write a message onto the paper. 4. Next, wait for the juice to dry. 5. Finally, heat the paper by holding it close to the light bulb to see the message. Lesson: Lemon juice is a substance that oxides and turns brown when heated. Other substances which work in the same way are orange juice, honey, milk, onion juice, vinegar, and wine. Invisible ink can also be made using chemical reactions or viewing the message with a UV light.

Artificial Water waves

Materials: 1.jelly crystals 2.small cups 3.iron filings 4.calcium chloride 5.zip lock bag 6.water 7.adult Steps: 1.First, Fill one cup with 9 ounces of water 2. Next add a scoop of jelly crystals to the water and wait until the crystals are fully grown. ( The crystals are done growing when there is no more water in the cup) 3. Then add 4 tablespoons of the full-grown jelly crystals to a Ziploc bag 4. Next add 1 tablespoon of iron filings to the bag 5. Then, add a one and a half tablespoons of calcium chloride 6.next, mix everything in the bag by squishing the bag with your fingers 7.then, when everything is mixed, seal the bag 8.finally, squish and squeeze the bag to feel the heat coming out from it Lesson: When the water and Iron is contacted with air, rust is made with a byproduct of heat. Calcium chloride and water produces an exothermic reaction which starts the oxidation of the iron.
