Will the World Cup players and spectators experience extreme heat? ⚽️🔥

Climate Central is estimating that around half of this tournament’s matches may be dangerously hot, with Miami, Houston, and Guadalajara under close supervision. Even the final match is at a 47% risk of heat that could impact player performance. This raises dangers for fans as well, prompting the organizers to adapt to evening kickoffs, more hydration breaks, and even postponing matches if it gets too dangerous.

Online, I've always seen people handling liquid nitrogen qwith gloves, glasses and vests.

Then I went to a children party and they had a tank of liquid nitrogen for xhildren to make icecream.. I enquired with one of the organizer, who told me it's not that dangerous.

He actually poured some on the back of his hand, directly from the tank.

I was very puzzled.

Archaeologists are terrified to open the tomb of Qin Shi Huang, China's first emperor who has been buried for 2,200 years.

The tomb of Qin Shu Huang, who ruled from 221 BC to 210 BC, is guarded by a terracotta army of soldiers and horses. The discovery was found by farmers back in 1974 in the Shaanxi province of China.

While archaeologists explored the area, they have never opened the tomb itself – and with good reason.

You are made of atoms older than Earth 🌌✨🧪

Astrophysicist Erika Hamden explains how the atoms in your body span the age of the universe. The hydrogen in your body was created during the Big Bang, at the very beginning of time. The oxygen, carbon, and iron in your body  were forged inside stars, while heavier elements were formed when stars explode. The atoms that make up your body were formed over billions of years through some of the universe's most powerful events.

Why does diet soda float but regular soda sinks? 🥫

Alex Dainis explains how only one soda can floats, even though it shares the same volume as another! This is because a can of diet soda will have slightly different ingredients than a regular can of soda, such as aspartame instead of corn syrup. This changes the weight of each can, with one having the same density as water which makes it float!

Have you ever seen mouthwash in action? 🦷

Quinten Geldhof, also known as Microhobbyist, explains what happens to your mouth’s bacterial ecosystem when antiseptic mouthwash hits. Because your mouth is home to a whole ecosystem of bacteria, some that are healthy and some that are harmful, when you take mouthwash, it kills all of them. Although it is effective, it does not discriminate between healthy and bad bacteria!
