The simple discovery that a piece of wire mesh can stop a flame in its tracks saved the lives of thousands of miners.

This demonstration shows how a simple lamp made of gauze could contain the open candle flames that miners used before 1815. With the safety lamp, any potential explosions would stay contained and never escalate to dangerous levels (although mining remained an extremely dangerous occupation).

Watch the whole demo and hear the full story here.

This is what it looks like when you use warm water to dispose of a little bit of liquid nitrogen on your roof terrace.

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 ¾ 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. A wooden skewer 2. A clothespin 3. 1 cup of water 4. 2-3 cups of sugar 5. A tall narrow glass

Steps: 1. First, clip the skewer into the clothespin so that it hangs down inside the glass and is 1 in from the bottom of the glass. 2. Next, remove the skewer and clothespin and put the aside. 3. Then, pour the water into a pan and boil it. 4. Next, pour ¼ cup of sugar into the boiling water and stir till it dissolves. 5. Then, keep adding more sugar, each time stirring until it dissolves. 6. Next, remove the heat and allow it to cool for 20 minutes. 7. Then, ask an adult to pour the mixture into the jar to the top. 8. Next, submerge the skewer into the glass so it is hanging straight down the miss without touching the sides. 9. Finally, put it somewhere where it would not be disturbed and wait for the sugar crystals grow over the next 3-7 days.

Lesson: When you mix water and sugar, you created a saturated mixture, which means that the water could only hold the sugar if it was very hot. As the water cools, the sugar turns into crystals on the skewer.

Mars used to be much more Earth-like than we once thought. The Curiosity rover recently discovered high levels of manganese oxide, which can only exist in oxygen-rich environments. This means Mars used to have as much oxygen as Earth and plenty of water on its surface. Source Source 2
