The mystery of the gravitational hole in the Indian Ocean finally solved!A « gravitational hole » in the Indian Ocean has puzzled scientists for years. Thanks to models of mantle convection, we now know that this phenomenon is due to a complex dance between mantle plumes and tectonic plates.This discovery sheds light on our understanding of the dynamics of the Earth’s mantle and changes in sea level. But other mysteries persist: how have these internal Earth processes changed over time? How did they integrate the evolution of the Earth’s surface? More research is needed. 🌍🔬🌊**#Science #Geophysics #Ocean #GravitationalHole

🧪 "Gas Collection for Emission Spectra: a favorite demonstration using my set of pure samples of hydrogen, nitrogen, and five noble gasses are subjected to the high-frequency pulsed field of a miniature Tesla coil."
"Each gas has a characteristic breakdown voltage and emission spectrum - note that Nitrogen has the highest breakdown voltage and only glows when very near the coil where the field is most intense whereas Neon and Helium have the lowest breakdown voltage and begin to glow many centimeters away from the coil."
"The color of each gas is due to a mix of the colors emitted from electron energy transitions specific to each element - the basis of spectroscopy. The Krypton tube also exhibits interesting oscillations with this particular Tesla coil."

👨🔬 "Poly Density Puzzle: @physicsfun favorite science brain teaser - white beads and blue beads "float" oddly separated beneath the surface of a clear liquid. If the contents are mixed by shaking the container, the white beads gather at the top and the blue sink to bottom! Adding to the mystery - after about 30 seconds the two layers of beads will have slowly moved back to the middle."
What is your guess as to the physics behind this behavior?

🔎 Spark Science (via @physicsfun): "the bright flashes of light emitted from a common sparkler are tiny bits of burning iron metal which can be caught and collected with a simple piece of paper as a net.
These tiny metal bits are hot (more than 1000 °C, 1800 °F) and become molten where surface tension then pulls them into spheres before they cool- seen here at 300x magnification. Although the sparks are very hot, they can’t burn paper (or skin) because they carry very little thermal energy due to their tiny mass- they cool very quickly."

Every person you tag has to stick their hand into the mouth of a wolf eel.
This video is intended to show the bite force of the wolf eel despite having its head removed from its body. Unfortunately, these fish are consumed in several countries around the world.

🕯️ Tea-Light Floating Engine: a candle powered super simple steam engine (🎥: by @physicsfun).
The engine is just a coil of copper tubing, filled with water. The ends of the tube are bent and directed to produce counter-clockwise rotation. Steam builds up pushing water out with an explosive jet- which then results in a partial vacuum in the coil which pulls more water in to repeat the process.
The water expulsion is in the form of jet directed out the end of the tube whereas the refill comes back in to the tube from a larger range of angles- so on balance the engine moves opposite to the direction of the jets.

This is what the Webb telescope's orbit looks like. 🔭
Instead of orbiting the Earth, Webb will orbit the Sun in line with the Earth, around a position in space nearly 1 million miles from us called Lagrange point 2 (L2).
At L2, Webb will have a “halo orbit." The gravitational pull from both Earth and the Sun will cause the telescope to orbit around the Lagrange point, as shown in this video. From this spot, Webb will always point away from the inner Solar System and be shielded from any heat sources that could affect its ability to collect infrared light.

How cool was that!?
Interestingly, female kangaroos are able to suckle two joeys simultaneously – one in the pouch and one outside, offering two different types of milk, as well as having an egg ready for implantation.
Only female kangaroos have pouches because they do the child rearing – male kangaroos have no need for a pouch as they can’t produce milk.

How stadium seats are restored.
In addition to scratches, the plastic resin has become oxidized due to UV exposure (these seats probably get lots of sunshine!). Red pigment is really hard to protect, and with heavy UV exposure it turns cloudy (paint on red cars can also suffer the same problem).
This torch is melting away the oxidized top layer, allowing fresh red plastic to flow across the surface.

The smoke of a candle after blowing it out.…
Smoke is a collection of airborne particulates and gasses emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass.
The naked eye detects particle sizes greater than 7 µm (micrometers). Visible particles emitted from a fire are referred to as smoke. Invisible particles are generally referred to as gas or fumes. This is best illustrated when toasting bread in a toaster. As the bread heats up, the products of combustion increase in size. The fumes initially produced are invisible but become visible if the toast is burnt.
When the flame goes out, the glowing wick has enough heat left to break up the wax molecules for a while, but not enough to burn the carbon, so you get a trail of smoke until it cools.

This frog might be the most unique one you’ve ever seen! Check out @skuttlesrock, a bloated African Albino Claw Frog. Most times when a frog is bloated it is due to fluid that circulates in the lymphatic system. As it fills the lymph nodes the fluid builds up outside of its normal area, which leads to bloating.
