In 2006, important astronomers gathered in Prague, to solve a major issue of their science. What is a planet, and what it’s not?
They ended up with these 3 criteria.
1. It has to be in orbit around the Sun,
2. it has sufficient mass to assume hydrostatic equilibrium (well, to have a nearly ...

Inspired by Marvels Thor and his unique hammer Mjölnir, electrical engineer Allen Pan, crafted a hammer that only he can lift… as long as the hammer is on a metal surface and made a video which is now viral. You guessed right, “Magnets Oh! “ is the word, but how exactly?
Pan decided that strong electro-magnets ...
About a month ago, we discussed bones and equations. Today we are talking muscles.
A new high tech accessory surfaced lately. It is an armband that promises that will make you control everything with your hand gestures. Pretty much like Tom Cruise in Minority report, but even cooler.
The basic principle is that while you ...
There is a new water purification system with small modular units, that claims that it uses the most natural way to purify water, without polluting the environment.
It gathers (any) water and it heats it with the help of some solar panels.
As it heats, it begins to evaporate and the resulting vapor rises to ...
There is an impressive video going viral lately. A concrete mixing machine, is dropping 4.000 liters of water on a parking lot and the concrete just magically absorbs it all.
It’s not a magic trick or CGI. It is a new type of super-absorbent concrete designed to soak up nearly 900 gallons of ...
More lasers this week, after the Laser Cutting post! Why? Because there is a new, futuristic gadget spreading over the internet these days. It is a shaving razor, but without… a steel razor. It has a laser. Yes, a laser, that cuts off hair, smoothly, precisely and painlessly.
How it works?
Wavelengths of light had ...
Laser cutting is a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications, but is also starting to be used by schools, small businesses, and hobbyists. It works by directing the output of a high-power laser most commonly through optics. A computer is used to analyze the pattern ...
Surface Tension - Capillary Action - Liquid in a vertical tube
Written by
on Sept. 25, 2015 .Last update on Sept. 28, 2015.
Earlier this week we talked about Capillary action and how it is applied in the “scientifically crafted” Space Glass of Ballantine’s.
Let’s talk about Surface tension in order to land on capillarity.
It is the elastic tendency of liquids which makes them acquire the least surface area possible. Surface tension is an important ...

Earlier this month, we wrote about the “Ballantine’s Space Glass”, and its free-fall in a free-fall tower. This time we are going to discuss the basic principle that this device is exploiting in order to function.
It is called “Capillary action”, and it was first discovered by Leonardo Da Vinci.
Capillary action is the ...

People are strange. And even when they try to help other people, they sometimes do very… weird stuff. Like a couple of inventors back in 1965, who tried to create a machine to help the women who have trouble giving birth to their children.
They filed a patent, which was surprisingly granted, for a machine ...
