Simple scientific experiments can made use of a variety of common objects and tools. One of them has frying oil. Cooking oil that has been used for frying multiple times should not be utilized for cooking again. Instead of throwing it out, use it to learn the basics of science through simple experiments.
What are the characteristics of cooking oil? Does it still have capillarity despite being concentrated? This simple experiment will explain it.
Tools and Materials of Simple Experiment – Knowing the Characteristics of Cooking Oil
- Cooking oil was used.
- Cotton bud
- Cans/containers was used for soap or candy or unused glass cups
- Aluminum foil packaging was used for toothpaste
Step of Simple Experiment – Knowing the Characteristics of Cooking Oil
1. Prepare tools and materials. Twist a cotton and wrap it around a cotton bud.
2. Make a hole in the lid of the soap container. Cover the top of the hole with the former toothpaste packaging
3. Pour the used cooking oil into the container
4. Insert the cotton into the hole in the lid of the container. Cover it with a container that already contains cooking oil
5. Drop a little cooking oil to the tip of the cotton. Leave it for about 15 minutes
6. Burn the cotton with a lighter
Look what happened. The flame on the cotton will last a long time. It’s different if the cotton is not smeared with oil and then burned, it will be scorched and burnt out.
If you look closely, the cotton that is submerged and functions like a wick changes, it appears that the cotton absorbs cooking oil even though the oil is a concentrated liquid.
Explain of Simple Experiment – Knowing the Characteristics of Cooking Oil
This simple experiment shows two important characteristics of cooking oil: it possesses capillary force, as seen by the oil rising onto the cotton wrapped in a cotton bud. The second property is that cooking oil is flammable. The persistence of the flame on the cotton that has absorbed the cooking oil shows this.
The results of this simple experiment can also be used as a simple oil lamp instead of a candle when the power goes out. Can also be used to repel flies if placed on the dining table because flies avoid heat and flames. In order to avoid things that are not desirable, this simple experiment to know the nature of cooking oil is better if accompanied by parents, considering the materials used are flammable materials.
