1. Water can boil and freeze at the same time!
It's Called the triple point of water. The triple point of water is at 0.01°C (273.16K, 32.01°F).
It occurs when the temperature is just right for the three phases of water(Gas, Water, Vapor).

2. Lasers can be turned
It is true that water can be trapped in a waterfall. That happens because of total internal reflection. This same thing happens in Fibre optic cables. The light goes through the cables because of the total internal reflection. As you can see in the picture.
3. We've got spacecraft hurtling towards the edge of our Solar System really, really fast
We all know rockets are fast, and space is big. But sometimes when we're talking about how long it takes for us to get to distant parts of the Solar System (eight months to get to Mars, are you kidding me?) it can feel like our spacecraft are just crawling along out there.
4. An egg does not mix with water!
If you break egg 18 meters below the ocean level the egg will not behave like a broken egg. It will as there is an invisible shell.
5. Pythagoras' theorem with fluid
You can prove Pythagoras' theorem by water. As you can see the water from the smaller square fully fills the bigger square as the theorem a²+b²=c²
6. What happens when a black hole swallows a star
As the star gets sucked up into the black hole, a huge jet of plasma is burped out, spanning hundreds of light-years. "When the star is ripped apart by the gravitational forces of the black hole, some part of the star's remains falls into the black hole, while the rest is ejected at high speeds," explains Johns Hopkins University researcher, Suvi Gezari.
7. This is how a face forms in the womb
At first, that was looking like a potato. Then slowly it turned into a face.
