Steel Wool Generating Heat experiment

Using vinegar to heat up steel wool Chemical reactions occur every day all around us. A chemical reaction is a process where one type of substance is chemically converted to another substance. That fizzling toilet bowl cleaner is a chemical reaction. The fire in your fireplace is another type of chemical reaction. The smoke that comes out of Dad's ears when you lose one of his favorite golf clubs is a result of a chemical reaction. OK, so maybe that's a bad example. This experiment demonstrates a chemical reaction that's fairly common all around us (and we don't have to touch Dad's golf clubs to make this one work). Put the thermometer in the jar and close the lid. Wait about 5 minutes and write…

Homemade fire extinguisher experiment

Homemade fire extinguisher Most people have fire extinguishers in their homes and in fact, we even place extra ones in the garage where Dad hangs out.  All schools and businesses are required by law to have fire extinguishers on their premises. Fire extinguishers work by removing one of the critical ingredients for a fire - oxygen. In this experiment we demonstrate this process. Fill the small dish with baking soda. Place a short candle and a slightly longer candle upright in the baking soda Place the dish into the bottom of the large bowl. Have Mom or Dad light both candles.  If Dad's handling the matches then go get that fire extinguisher out of the garage first. Pour the vinegar into the dish of baking…

Making homemade plastic science experiment

Making homemade plastic Yep, we're surrounded by plastic.  Sit right there and look around the room and see if you can spot something made of plastic.  See, I told you so. The keys on your keyboard are made of plastic.  The mouse you've got your hand resting on is made of plastic.   Even parts of the monitor you're looking at right now is made of plastic ( Reeko,  I don't know how you know all these things but stop it - it's giving me the creeps). These plastics can be either natural plastics which are made of materials such as wax or natural rubber, or they can be synthetic plastics which are made from polyethylene or nylon.  Most plastic is made of petroleum oil.  The…

Magic balloon egg

Magical fun with eggs If you're the type of person who finds yourself shouting, "I want and I want it NOW" then this experiment might not be for you. It'll take 10 days to see the results of our experiment but when all is said and done, we'll have one of the weirdest eggs you've ever seen. Magicians have created eggs like the one we're about to make, for many years. As early as 1900, magicians created these "magic eggs" and used them as props in a variety of magic tricks. Imagine if you could remove the "hardness" from an egg shell giving you an egg that could be folded like a napkin or blown up like a balloon? The egg could be folded to…

Blow up balloon

Blow up balloon with baking soda and vinegar When vinegar is mixed with baking soda, a double replacement reaction takes place. The end result is carbon dioxide but behind the scenes, there is more than one reaction taking place. Put a tablespoon of backing soda on to the center of a paper towel. Fold the paper towel over the baking soda a few times. The objective is to create a “time release” mechanism for our reaction. Pour ½ cup vinegar into a plastic bag. Pour ¼ cup warm water into the back with the vinegar. Hold the baking soda filled paper towel in the mouth of the plastic bag by pinching the sides to hold it. Don’t let the paper towel touch the solution yet.…
