Dead or depleted batteries, especially cylindrical ones like AA or AAA batteries, can exhibit a unique behavior known as "bouncing" when dropped from a short height. This phenomenon is primarily due to changes in the battery's internal chemistry and physical properties as it becomes discharged.

Inside a battery, there are chemical reactions that generate electrical energy. As a battery discharges and its chemical energy is depleted, its internal chemistry changes. One of the changes that occur is a reduction in the pressure of gases within the battery. This decrease in gas pressure can make the battery feel lighter, contributing to its bounce.

As a battery discharges, its internal components, such as the cathode, anode, and electrolyte, unde ...

Start by watching the video below In the video, a Japanese man converts plastic waste into usable oil and fuel using a machine that thermochemically decomposes the plastic in a process known as pyrolysis.



Pyrolysis works by thermochemically breaking down material at temperatures above 350 degrees Celsius in the absence of water. This not only physically melts down an object, but also changes its chemical composition so that, in the case of plastic waste, it reverts back into boiling liquid and eventually gas.

Nitrogen triiodide (NI3) is a contact explosive that sets off whether it comes in contact with a feather or a bug. As shown in the diagram, the chemical is made up of a cluster of three iodine atoms around one side of a nitrogen atom. The result of such a crowd around one atom causes something called bond strain - the atoms repel each other in a small space. The result of this bond strain is that the molecule is prone to falling apart very, causing the mini explosion you see ().

Since its discovery in 2010, researchers have been trying to solve the mystery of dark streaks that appear and disappear seasonally on the planet's surface (shown above). Scientists are now claiming that this phenomenon, known as the recurring slope lineae, is caused by a bath of saltwater. What is still unknown, however, is where the water is coming from, or if the chemistry is even right for supporting life.
