Thank you for taking the time to enjoy the The Forgotten Concept Cars of the 60's (Part 2) post. Go right here if you missed it. This is my favourite concept car of the 50's. You guessed it, TFCCotY 50's is coming next week! :D Well… Only if the Kinja update doesn't go live over the weekend. (more after the jump)
Food Science: Gummy Bears are responsible for obesity. Here's how to execute a Gummy Bear as inhumanely as possible.
Difficulty level (1-5): 1
Time: About 15 minutes
Safe for kids: No
What you need:
- 1 Gummy Bear (make sure it's not sugar-free)
- 3mg (about 1 tsp) Potassium chlorate (KClO3)
- Large test tube
- Support Stand with an adjustable test tube holder
- Butane micro burner or Busen burner (if you don't have them, an alcohol lamp burner or a candle will do)
- Laboratory goggles
Note: It is recommended to perform this experiment under a fume hood or outdoors if you don't have it.
- Put the test tube in the test tube holder at a 45º angle.
- Add potassium chlorate.
- Put on the laboratory goggles.
- Bring the flame directly under the test tube to bring the salt to a boil.
- Turn off the source of flame.
- Use tweezers to carefully insert the Gummy Bear down the test tube.
- Watch in absolute delight as the Gummy Bear bursts into flames!
- Announce the time of death (optional)
Let the test tube sit to cool for a few minutes before you can throw it away. It won't be reusable because the heat will cause the salt to melt into the glass.
When potassium chlorate is heated at a high temperature, it decomposes into oxygen gas and potassium chloride (KCl) salt. The salt is rich in oxygen, which is a strong oxidiser. The Gummy Bear is rich in sugar, which is a carbohydrate, a compound that is made up of carbon, hydrogen, and oxygen molecules. The molten salt will react violently to the presence of carbon, which is considered dirty. Carbohydrate compounds will be broken into three molecules. What happens when hydrogen gas is ignited by the heat? It produces more flames. The flame is purple due to the presence of potassium metal in the solution.
Have a great weekend, Opponauts of the western hemisphere, cheers! :)
