Science Facts that willl blow your mind !

1. A laser can get trapped in          water

A cool thing called “total internal reflection” happens when you point a laser beam at a jet of flowing water.

2. A cloud can weigh around a      million pounds

Your childhood dreams of floating on a weightless cloud may not withstand this science fact: The average cumulus cloud can weigh up to a million pounds, according to the USGS. That’s about as heavy as the world’s largest jet when it’s completely full of cargo and passengers.

3. Hot water freezes faster than cold water

This may seem counterintuitive, but it’s called the Mpemba effect. Scientists now believe this is because the velocities of water particles have a specific disposition while they’re hot that allows them to freeze more readily.

4. Water can exist in three states at once

This is called the triple boil—or triple point—and it is a specific temperature and pressure where materials exist as a gas, a liquid, and a solid simultaneously. The triple point, which is also the only situation where all three states of matter can coexist, is different for every material. Water reaches its triple point at just above freezing (0.1 degree Celsius) and at a pressure of 0.006 atm.

5. About half of your body is bacteria

Experts estimate that the human body consists of 39 trillion bacteria and 30 trillion human cells—a roughly 1:1.3 ratio. In the past, researchers thought we were much more bacteria than human, with a ratio of 10:1.

6. Men are more likely to be colorblind than women

The genes responsible for the most common type of colorblindness are found on the X chromosome, the National Eye Institute explains. Even if women have the genes on one of their two X chromosomes, a properly functioning gene on the other one makes up for that loss. If men inherit the gene on their only X chromosome, they’ll become colorblind.

7.A cockroach can live for up to one week without its head

Cockroaches are infamous for their tenacity and are often pointed to as the most possible nuclear war refugees.

Due to their open circulatory system, and the fact that they breathe through little holes in each of their body segments, they are not dependent on the mouth or head to breathe.
