This homemade slime recipe forms a slippery, slimy colloid and is the best DIY slime you can make at home. You will need to purchase some polyvinyl alcohol, but that’s what makes this work so well. We ordered ours online for five buck a bottle, but you may be able to find it somewhere locally. There’s lots of slime recipes that include ingredients you can get from the store. This one takes a little preparation, but it’s worth the time. Get on it!
1 1 oz bottle of 2% polyvinyl alcohol solution
1 1ox bottle of 2% sodium tetraborate solution (borax)
How To Make Homemade Slime
- Pour half of the bottle of polyvinyl alcohol into the cup.
- Add one capful of sodium tetraborate. Stir vigorously for thirty seconds. If it’s too runny, add a few more drops of sodium tetraborate. If you add too much of the sodium tetraborate your slime will become brittle and crumbly.
- Play with it. Throw it all the wall. Throw it at you mom. Run like crazy.
- Put it in a sealable bag and save it for later.
We used this recipe for a science fair project. The idea was to make slime from three different recipes and observe their properties. I’m sure we ended up with some kind of ribbon. By “we” of course I mean my young son.
The National Content Standards for Primary Chemistry are listed below. This activity has been correlated to these standards.
A. Properties of Objects and Materials
- Objects have many observable properties, including size, weight, shape, color, temperature, and the ability to react with other substances; those properties can be measured using tools, such as rulers, balances, and thermometers.
- Objects are made from one or more materials, such as paper, wood, and metal. Objects can be described by the properties of the materials from which they are made, and those properties can be used to separate or sort a group of objects or materials.
- Materials can exist in different states, solid, liquid, and gas. Some common materials, such as water, can be changed from one state to the other using heating or cooling.
