Unflavored gelatin has plenty of uses in the kitchen. One of its main uses is for the binding in pies, jams and cream cheeses. It’s also used to make the capsules for pharmaceutical pills, photo papers, soft drinks and cosmetics. Because of the many different uses of unflavored gelatin, plenty of people like to use it for projects.
Things You'll Need
Boil a cup of water. Once it is boiling, transfer the water to a bowl. Then the gelatin needs to be added.
Pour in one envelope of gelatin. Stir very quickly and constantly, it will gel up very quickly.
Add a cup of cold water to the gelatin.
Stir the gelatin and put it in the refrigerator. It needs to be refrigerated for about 3 hours.
For thicker gel, add 1/2 cup of water to boil and a 1/2 cup of cold water to bowl.
Science projects that use unflavored gelatin:
- GERMINATE SEEDS: Fill a small jar with 3/4 inch of the gelatin. Place some seeds into the jar and add several drops of house plant fertilizer in liquid form. This is great because the seeds won’t need to be water and every part of the plant (including roots) will be completely visible and easily observed.
- GROW CRYSTALS: Pour the water into a saucepan, sprinkle some unflavored gelatin into the water and allow it to soak in. Heat the saucepan up and stir the water until the gelatin is dissolved. Add sugar to the water and continue stirring until the sugar is dissolved. Cool the water for 5 minutes and pour it into a jar. Track the experiment and watch as crystals form in the solution.
- BACTERIA CULTURES: Boil water. Add 1 tsp of unflavored gelatin and 1 tsp of sugar to the water. Stir until the gelatin and sugar have dissolved. Cool for ten minutes, then pour into a jar and cover with lid. Wait 2 hours for the gelatin to firm. Use a cotton ball to swab the dirty surface of a household object and rub the cotton over the gelatin “culture” area. Wait 24-48 hours, and watch the bacteria start to grow.
