Immitation Caviar

Explore the chemical structure of gelatin by showing you how to make imitation caviar. Delving into the world of molecular gastronomy, we will learn spherification using cold oil, the chemical properties that make gelatin so interesting, and most importantly how to make imitation caviar! For this experiment you will need your favorite liquid (I used pineapple juice), gelatin, vegetable oil, and an eyedropper.

DNA Extraction

 

how to extract DNA from strawberries using household products (salt, soap, water). DNA extraction occurs through 3 steps: lysis, precipitation, purification. This technique can be used in forensic units within the police force and preventative medicine since it can be used for anything that contains cells since that is what houses DNA (plants, fruits, vegetables, bacteria, viruses, skin, blood, saliva etc). 2-3 strawberries, ½ cup of water, 1 coffee filter, ½ cup of rubbing alcohol, 1 clear cup, 1 tsp of salt, 2 tsp of detergent, 1 sandwich bag.
