How to Make Liquid Magnets Video Making a liquid magnet results in something that looks straight from a science-fiction movie! Find out how to do this cool chemistry trick in this how-to video from About.com.See Transcript Hi, this is Ben Roy for About.com, and today I'm going to show you how to make a liquid magnet. Materials to Make a Liquid Magnet You will need: A magnet Vegetable OilLaser Jet toner How to Make a Liquid Magnet You want to pour a decent, but small amount of toner in a glass. Take your magnet and put it to the glass. You will see spikes because the liquid is attempting line up with the otherwise invisible magnetic points of the magnetic field that is being created.

Make a Snowflake What you'll need: String Wide mouth jar White pipe cleaners Blue food coloring (optional) Boiling water (take care or better still get an adult to help) Borax Small wooden rod or pencil Instructions: Grab a white pipe cleaner and cut it into three sections of the same size. What's happening? Crystals are made up of molecules arranged in a repeating pattern that extends in all three dimensions. When you add the borax to the boiling water you can dissolve more than you could if you were adding it to cold water, this is because warmer water molecules move around faster and are more spread apart, allowing more room for the borax crystals to dissolve. When the solution cools, the water molecules move closer together and it can't hold as much of the borax solution.

How to Make Silly Putty Video Silly putty can be made with common household objects, and is a great chemistry experiment to do with kids. Get two different methods for making homemade silly putty in this video from About.com.See Transcript Hi, I'm James Clinard for About.com. Today I'm going to show you two different methods of making silly putty. How to Make Silly Putty with Borax For the first method, you'll need: 1/4 cup of glue3/8 cup of water1 tablespoon of borax Make a 50-50 mixture of glue and water using one quarter cup of glue and one quarter cup of water. Next, dissolve the borax in 1/8 cup of water. How to Make Silly Putty with Liquid Starch For the second method, you'll need: 1/4 quarter cup liquid starch 1/2 cup glue Pour the liquid starch into a bowl, and then add in the glue. Whichever method you choose, keep your silly putty in a sealed plastic bag when you're not using it so that it doesn't harden. Making silly putty is a fun activity that also demonstrates some basic principles of chemistry.
CD Hovercraft An old CD or DVD disc A 9” balloon A pop-top cap from a liquid soap bottle or a water bottle A hot glue gu If you are using the cap from a water bottle, cover the center hole of the CD with a piece of tape and poke about 6 holes in the tape with a push-pin or small nail. This will slow down the flow of air and allow your hovercraft to hover longer. Use the hot glue gun to glue the cap to the center of the CD or DVD disc. Create a good seal to keep air from escaping. The air flow created by the balloon causes a cushion of moving air between the disc and the surface. The project above is a DEMONSTRATION. 1. 2. 3.
Think! Summer Fun: Microwaved Ivory Soap | Wendolonia When I came across the idea to microwave Ivory soap on The Cyber School Mom Diary’s fantastically comprehensive Supermegatotally Thrilladelic Not Bummer Summer list, I was instantly intrigued. “What happens when you microwave Ivory soap?” I asked. “Try it and see!” I immediately added it to our summer fun list and once Wyatt saw it he was dying to see what happened. Soap! It definitely did not disappoint. We started off with a hunk of plain old Ivory soap . How cool is that? I’d also like to take a moment to note that I’m mortified by how dirty my microwave is in this picture. Anyhoo, the kids were thrilled by this project and have been begging me to do it again since the first exciting result. Have you ever microwaved Ivory soap? If you’re visiting Wendolonia for the first you may be interested in checking out some of my other kid-centric posts:
Straw Hoop Plane A regular plastic drinking straw 3 X 5 inch index card or stiff paper Tape Scissors 1. Cut the index card or stiff paper into 3 separate pieces that measure 1 inch (2.5 cm) by 5 inches (13 cm.) 2. Take 2 of the pieces of paper and tape them together into a hoop as shown. 5. Can we really call that a plane? The project above is a DEMONSTRATION. 1. 2. 3. 4.
How to Make a Hula Hoop How to Make a Collapsible Hoop: Since I've been getting quite a few requests for collapsible hoop-making instructions lately, here are the basics. In addition to what you need to make a regular hoop, to make a collapsible, you need: Four connectors per hoop instead of oneBulk bungee corduncoated coat hanger wirea power sander (or a lot of patience)several pairs of pliers and several hands Fair warning on two points: First, sanding down the connectors produces plastic dust that you do not want in your eyes or lungs. Here's how it works: Measure off a length of tubing to your desired hoop size, and cut. Heat one end of each of the four tubes, and slide the non-sanded ends of the connectors into each, up to the halfway point, leaving the sanded ends sticking out. You should be able to pull the hoop apart with some effort, but when spinning at top speed it should stay together.
Easter Craft for Kids {Absorption Art Absorption art is one of our favorite ways to create. It is such a simple way to let kids explore with art, and only a few supplies are needed. The other day I set up an invitation to create Easter eggs with absorption art, and all four of my boys loved creating. Supplies: JZ (5) squirted the liquid watercolors into the containers. Prepare the invitation to create with absorption art, then invite your children to begin making glue designs. J-Bug (3) was content with a small amount of glue. Shake off any excess salt then drop colored water onto the glue and salt mixture. Using pipettes or eye droppers is a great exercise for developing fine motor skills. JZ made it a personal goal to see how much colored water he could suck up into the pipette. Tank and Peanut (20 months) have shown a lot of interest in our art projects lately. I expect a mess when crafting with toddlers, but I do my best to establish good habits. For best results allow the paper to dry. More Easter activities for kids:
Static Tinsel Levitating Orb 1 inch (2.5 cm) wide PVC Pipe about 24 inches (60cm) long. You can also use a regular balloon if you do not have PVC pipe. Mylar tinsel for Christmas trees. There are many types of tinsel - you should look for the thinnest and narrowest possible. The tinsel used in the video is about 1 millimeter wide. 1. It is all about static charges. The project above is a DEMONSTRATION. 1. CLICK HERE to watch student-made videos of the static orb in action.
