Introduction It’s not difficult to set up a chemistry lab. Chemistry equipment is quite affordable and more expensive equipment (i.e. > $30) can be purchased piece-by-piece until your home laboratory is complete. Below is everything you need to know about setting up a home chemistry lab including a complete list of suggested laboratory equipment for your chemistry lab, chemicals for your lab and how to obtain them, and how to safely organize and store chemicals in your lab. Chemistry lab equipment The following is a list of chemistry lab equipment found in a functional chemistry lab. Clicking on the image will take you to Reeko's recommended product on Amazon. Reeko earns revenue on each item purchased through Amazon which is how he affords to live in a giant mansion in the Bahamas, own several private
When conducting chemistry experiments, it's helpful to have in hand a list of chemical names, their chemical formula, storage code, and mass and density. Also, since many chemicals are known by alternate names, and often found in local retailers such as hardware stores, grocery stores, or plant stores, a list that reveals the common name behind these chemicals can save you a lot of money. Reeko has you covered! Click here for a complete chemical list you can use as a reference when conducting chemistry experiments, shopping for chemical supplies, and storing chemical at home. If you find a missing chemical that you would like added, shoot Reeko an email and he'll add it to the list.
They tower nearly two stories tall (up to 20 feet), weigh well over 2,000 pounds, and stand on long, lanky legs that let them reach speeds up to 40 mph. But with such a massive, gangly frame, how do they lay down to sleep? First, to lie down, the giraffe kneels on its front legs, folding them under its body, and then lowers its body to the ground, sort of like an accordion. Getting back up is pretty much the opposite process – the giraffe first gets on its knees and then spreads its hind legs to raise its back-end to full height. Then they straighten their front legs and viola, they’re back upright again. Luckily giraffes don’t have to do this awkward routine very often –
Water, frozen into a solid state - we see it on the ground in the winter, on top of mountains, and in our refrigerators – but how often have you thought about how marvelous ice is? In our Solar System, ice is abundant and found naturally on most of the planets. On Earth, it plays a key role in our water cycle and climate. And yes, it can be beautiful! Check out the pictorial gallery below for wonderfully striking images of ice sculptures found all around us. Click on a picture to start the gallery.
They can be scary, ugly, cute, and funny. They’re a critical part of our ecosystem, required for the very survival of mankind – animals! Here’s Reeko’s salute to those fuzzy (and feathery) creatures we all love oh so much. Check out the animal pictorial below (click picture for larger version).
It is said that a picture is worth a thousand words. In these interesting science pictures, they are worth a single word – “huh?”. Check out the cool science pictures below. If they don’t cause you to scratch your head in wonder, they will at least put things in perspective. The sun in a different light This picture of the sun was taken using a different wavelength filter giving us an entirely different perspective. How big is the moon? The surface area of the moon is 37.9 million square kilometers. How big is that? Here’s a true-scale image of the United States superimposed over the moon. How do astronauts eat in space? Below is a food tray used aboard the Space Shuttle. Notice the velcro used to hold the food in
Wow - you can't get enough of insects!!!. They’re creepy, icky, and tickle when they crawl through your hair but with an estimated 10,000,000,000,000,000,000 bugs and spiders crawling around on the planet, you might as well get used to them. Besides, some bugs and spiders are actually quite pretty. No? Check out the pictures below.

An Aurora is a beautiful natural light display in the sky that occurs above the magnetic poles in the northern and southern hemispheres (in the Arctic or Antarctic regions). In northern areas of the world, the lights are known as aurora borealis (or northern lights). In southern areas, the lights are known as aurora australis (or southern lights). The northern lights are often visible in Alaska, Russia, and Canada. The southern lights are often visible from Antarctica, South America, New Zealand, and Australia. During a geomagnetic storm, the lights can spread to other lower latitude areas. The northern and southern lights are caused by energetic charged particles from the sun colliding with gas particles in the sky. These charged particles arrive from the sun via solar
