IV's are used on patients to either administer fluids or medicines, and for a nurse, it's the number one task performed on the job in a hospital. Knowing the proper procedure for peripheral intravenous catheter insertion is a must. This interactive video module will help familiarize you with the medical procedure, but is not meant to be your sole method of instruction— always ask for supervision in performing a procedure if you've never done one before, or have little experience.
In this video you are shown step by step the proper way to administer the insulin to your cat. We show you how to properly prepare the insulin, fill the syringe, and inject the cat. Give an insulin shot to your cat.
In this video watch Michael Zbyszynksi, explain how to make carrot caviar in this video. He starts with a beaker of ordinary carrot juice mixed with sodium alginate -- a derivative of seaweed -- at a ratio of 2 grams of sodium alginate to 250 grams of carrot juice (a 0.8 percent solution). He then uses a syringe to drop small beads of the solution into a bath of water with a couple grams of calcium chloride dissolved in it. The calcium chloride hardens the sodium alginate from the outside in,...
Scientific studies have shown that species with large swimbladders, especially bottom dwelling fish such as grouper and snapper, derive an immediate benefit from venting.
I first heard the term molecular gastronomy while watching an episode of Bravo's Top Chef a few seasons back. Intrigued by the concept, I sought to find out more about this modern, deconstructed type of cookery. If you happen to be around foodies and the topic of molecular gastronomy comes up (which very likely will at some point) you'll want to have a few points to contribute and maybe even give them a run for their money.
His name is Don Pettit, but I like to call him Space MacGyver. He's well known for his paper clip fixes and ingenious coffee invention in zero gravity, and we've all seen the NASA astronaut in his Saturday Morning Science videos during his first stay on the International Space Station. And now he's back on the ISS with a brand new physics-related show... Science Off the Sphere.
If you have an earache, look no further than your kitchen or medicine cabinet. For a non-intrusive remedy, simply rub a little Vicks VapoRub along the outer part of your ear (never inside the ear canal) and place a heating pad over the affected ear.
Whenever we make a homemade circuit, we use what are called through-hole components. Any components with long metal leads is a through-hole component. They are great for soldering to, but it's tough to fit enough through-hole resistors and capacitors into a smartphone. To get those last microns, we have surface-mount components for SMDs (surface-mount devices). These are all of those teeny, tiny things you see when you crack open your digital camera or laptop case.
The ancient craft of origami gets an update in Oritsunagumono, where environmentalism meets photoelectricity for the first time. Its name translates into "things folded and connected," and its agenda aims to bring awareness of the environmental impact of pollution to native marine wildlife in Japan's coastal waterways.
How small is Russian artist Anatoly Konenko's microminiature aquarium? Well, for starters, it holds just two tablespoons of water. Not that you could ever fill it with a spoon, of course! The force would tear the décor to bits. Konenko favors a syringe for that particular task.
Evil Mad Scientist Laboratories has figured out a way to make an omelette inside the eggshell through a tiny, punctured hole.
When he's not taking orbital videos of Earth's auroras, NASA Astronaut Don Pettit is experimenting with water in zero gravity. He's already shown us how water droplets can orbit around knitting needles in a microgravity environment. Now he's playing with water again, this time—antibubbles.
Giveaway Tuesdays has officially ended! But don't sweat it, WonderHowTo has another World that's taken its place. Every Tuesday, Phone Snap! invites you to show off your cell phone photography skills.
