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 ...
Recently a patient in Spain received recently, a 3D printed titanium sternum and ribs as an implant.
Due to the patient’s condition, doctors needed to cut and remove the sternum and some ribs. Usually, they are being replaced by a titanium plate, which is becoming unstable after a certain amount of time. But this ...
Projectiles and Self-healing materials

Recently NASA revealed a fascinating new material, that it heals itself in a couple of seconds, after being penetrated by a projectile.
It might sound like a science fiction movie, but It isn’t.
How it works? The material is made up of three layers—two thin polymer walls with a liquid inside—which, when ...
Lately, the Ballantine’s Whiskey brand invented a whiskey glass which can be used in zero gravity situations. They call it “Space Glass” and in order to test its functionality they had to use a drop tower.
In physics and materials science, a drop tower or drop tube is a structure used to produce a ...
MIT has a team called Mediated Matter, which is led by the brilliant Architect and Professor, Neri Oxman. Her team recently unveiled a 3D printer they developed which uses a very old, but new in the 3D printing world, material. Glass!
She stated that this technology has potential for applications on a much larger scale ...
