How To: Create a plankton science model

In this tutorial, we learn how to create a plankton science model. You will first need a clear bucket with water, modeling clay, toothpicks, sponge, beads, buttons, pipe cleaners, Styrofoam peanuts, and more. To make the plankton, you will first take the peanut and stick a toothpick into it. Then, add a paperclip on top of that to give it some weight. Drop it into the water and see if it floats or sinks. Add some more weight to it to see how much weight it takes to sink it to the bottom. Have...

News: Stem Cell Research to Grow Bigger Boobs

A recent Japanese study proposes a simpler, softer, more natural-feeling alternative to silicone breast implants: fat-derived stem cells. The cells are extracted from liposuctioned fat, and then injected into the patient to increase breast circumference. San Diego-based biotech company Cytori Therapeutics is currently waiting on FDA approval to start clinical trials.

How To: Make an amazing floating static orb

Learn how to make this spooky, amazing floating static orb. This is so simple, and so cool. It uses static electricity to make a tinsel orb levitate above a PVC pipe. We've gotten the orb to float for over 10 minutes. We just discovered you can use a regular balloon instead of the PVC pipe, but we like the pipe best. Watch the video, and then make your own!

How To: Take an acid and base to make salt

In this tutorial we learn how to take an acid and base to make salt. To start, you will first need to take an acid of your choice, this can be something like vinegar. After this, you will combine the acid with a base and then wait for it to react. Once it starts to react, gases will release from them and you will end up with some salt! Be sure to put a cap on the container while the reaction is happening. This will allow the reactions to come together and the gases to react. Have fun and do t...

How To: Balance chemical equations using a simple method

In this video, we learn how to balance chemical equations using a simple method. Start out by writing your two chemicals next to each other. After this, you will need to write out how much of each atom each of the chemicals has. Now you will have a better idea of how you need to balance out each of the different equations. Make a chart of all the elements that are involved, then you can solve it. Use simple addition to add together the atoms of each and then write out the correct answer in th...

How To: Fireproof a balloon

In this tutorial, we learn how to fireproof a balloon. Usually, if you bring fire to a balloon it will pop, but there's a way to avoid this! First, get your balloon and place it around the nozzle of your sink. Then, fill it up with water until you have a decent amount of water. Now, blow some air into the balloon and tie at the end. From here, put your balloon to the test! Place a lighter underneath the balloon to see how it reacts. It should not pop like it did before. The water will absorb ...

How To: Make hydrochloric acid from salt

In this tutorial, we learn how to make hydrochloric acid from salt. First, you will pour some salt into a distil flask. After this, you will add in some concentrated sulfuric acid to the salt. Next, you will let these react with each other. You will start to see gasses bubble up and the excess hydrogen chloride gas come out through the top of the tube. To create a stronger reaction, you can add heat underneath the reaction. Then, test this by exposing it to ammonium chloride. If it's the righ...

How To: Build a wave machine out of household items

In this tutorial, we learn how to build a wave machine out of household items. You will need: 20 straws, 40 paper clips, 2 pieces of tape, and 1 washer to make this. First, you will need to pull out a long string of tape and lay it down with the sticky side up. After this, you will need to stick the straws on top of the tape in a row all going next to each other. Do this from the top to the bottom until all of the straws are stuck on. Then, stick the washer to the top and you are finished wit...

How To: Build parachutes with household materials

In this video, we learn how to build parachutes with household materials. You will need: a long string, Mylar, mesh, plastic, scissors, tape, and a weight. To get started, you will first cut your plastic or mesh into a circle or octagon shape. Then, take your string and cut it into several pieces. Then, tape the strings onto your material all around. After this, tie your weight to the strings so it's fully secured. Now, go to somewhere high and throw down your item! The parachute will help ke...

How To: Star gaze with your kids

In this video, Daddy Troy teaches us how to star gaze with your kids. This can get your kids interested in space and teach them a thing or two, while still having a good time. First, Google offers a service called Google Earth, which will show your child the entire earth, moon, and mars. Kids can use these programs just like a video game. They can see real pictures as well as their own home or grandma's home. This is free and a lot of fun! Next, you can see satellites with your naked eye in t...

How To: Make polymer putty with household materials

In this tutorial, we learn how to make polymer putty with household materials. You will need: borax, white glue, water, 3 plastic cups and spoons, and food coloring to color your putty. Now, dissolve 4 tbsp of Borax in 2 liters of warm water. Then, prepare equal parts of glue and water together. To make this, you will need 2 parts of the glue solution to 1 part of the Borax solution. Once you mix these together, you can add in some food coloring to it. Pour this into different cups to make di...

How To: Make iron sulfide with sulfur and iron

In this home-science how-to from Household Hacker, we learn how to create an exothermic reaction by combining sulfur with iron, producing iron sulfide in the process. For all of the details, including step-by-step instructions, as well as to see what happens when these two elements meet, watch this video guide.

How To: Make bubbling acid with ammonia and dry ice

In the mood for a little mad science? In this home-science how-to from Steve Spangler, we learn how to prepare a bubbly, color-changing concoction using water, ammonia, a universal indicator (cabbage juice will do fine), dry ice, gloves and two plastic cups. Now, repeat the process, this time adding a teaspoon of ammonia when you add your universal pH indicator.

Do Not Try This At Home: The Human Torch

PopSci's Gray Matter demonstrates again and again what the layman should absolutely Not Try at Home. Which is precisely what makes Gray's experiments so fun. Remember when the mad scientist fully submerged his hand in liquid nitrogen? Today's demonstration also plays with what is (quite reasonably) assumed to be extremely dangerous and painful: torching the human hand.

How To: Make copper metal from copper sulfate

This free video science lesson from the Home Scientist demonstrates a simple technique for creating ammonium chloride from hydrochloric acid and ammonia. For all of the relevant details and detailed, step-by-step instructions, as well as to get started trying this experiment yourself, watch this home-science how-to.

How To: Mod a Bresser Biolux NG or AL microscope to view larger objects
