The Camera Lens Mug

A cup of joe that’ll keep you sharp, in-focus, and happy all day long…and those side effects aren’t from the caffeine.

Behold, the Camera Lens Mug, a mug that looks JUST LIKE a Canon 24-105mm lens!

It's equipped with a lens-cap lid, rubber-grip focus and zoom rings, and an auto-focus switch that actually switches

Make Glow Sticks - The Science

From NurdRage
We show how to make glow sticks and go through all the chemicals needed as well as how to make different colors. We also talk about the chemistry and scientifically research a proposed mechanism.

To make the glow stick mix together the following:

10mL Diethyl Phthalate (solvent)
3mg of fluorescent dye (see below)
50mg TCPO (see below)
100mg sodium acetate
3mL 30% hydrogen peroxide (add last to start reaction)

The fluorescent dye can be 9,10-bis(phenylethynyl)anthracene for green, Rubrene for yellow, 9,10-diphenylanthracene for blue, and rhodamine B for red.

TCPO is expensive to buy but can be made for much cheaper by following the directions in our previous video: http://www.youtube.com/watch?v=ViJknv...

The chemicals, including the ones to make TCPO were purchased from alfa aesar: http://www.alfa.com

The Rhodamine B and Rubrene dyes were instead purchased from sigma Aldrich: http://www.sigmaaldrich.com/

The dyes and TCPO are carcinogenic and gloves should be worn when handling them.

The TCPO and sodium acetate amounts can be varied considerably and still obtain good light. Smaller quantities tend to be dimmer and decay faster, while larger quantities last longer.

For those of you higher level individuals that actually do want to know the mechanism for this process, please refer to this article: http://pubs.acs.org/doi/pdf/10.1021/j...

Liquid armour 'can stop bullets'

Liquid armour 'can stop bullets'

A liquid armour has been shown to stop bullets in tests carried out by UK scientists at BAE systems in Bristol.

The researchers have combined this "shear-thickening" liquid with Kevlar to create a new bullet-proof material.

The company is keeping the chemical formula of the liquid a secret, but it works by absorbing the force of the bullet strike and responding to it by becoming much thicker and more sticky.

The BAE scientists describe it as "bullet-proof custard".

eCube® is an Energy-Saving Device for Commercial Refrigerators.

How eCube® works

eCube® consists of a food simulant contained in a double-skinned enclosure that mimics food temperature at approximately 15mm beneath the surface.  With eCube®, the thermostat regulates the refrigeration temperature based upon food temperature rather than air temperature, thereby maintaining food at the proper temperature.  When fitted to the thermostat sensor, which controls the compressor, eCube® significantly reduces the frequency of the refrigeration cycles which are now based on food temperature rather than fluctuating air temperature.  By using eCube® as a cycle control mechanism, refrigeration cycles last longer but can be reduced by as much as 85%.  For example, a Dairy Case cycles 3 minutes on, 2 minutes off = 12 cycles per hour.  With eCube®, the cycles change to 8 minutes on, 7 minutes off = 4 cycles per hour; a 66.7% reduction in starts.  As the start-up of a refrigerator compressor uses 3 times more power (i.e. start-up 12 amps, run 4 amps) considerable energy savings are achieved.  In addition, the more efficient refrigeration cycle leads to a more efficient unit, which then leads to a colder storage area. Consequently, by re-adjusting the thermostat back to its normal temperature settings, there are further substantial energy savings, without compromising food safety and quality.
