I wondered whether we can make something comparable from gelatin or agar.
Homemade Magic Orbs- starrkingschool.net (agar orbs ~ above left, gelatin orbs on right)
A fast search online proved me that part chefs use a method called oil spherification to make tiny round morsels using everything indigenous balsamic vinegar to fruit juice, blended with gelatin and agar. It’s recognized to cooks as a “molecular gastronomy” technique, and also takes benefit of the truth that water and also oil don’t mix. Water-based droplets falling with chilled oil form into perfect spheres as result of surface tension, and gelatin and also agar added to the mix space colloids that solidify together they cool.
Magic Orbs creating in cold oil (starrkingschool.net)
We make some funny (inedible) orbs of our own, utilizing the technique: standard orbs (from gelatin or agar and water), floating orbs (with agar and also vinegar) and also color-changing acid/base indicator orbs (from red cabbage juice and gelatin or agar.) Adult supervision is compelled for this project, because it involves hot liquids. The orbs may likewise be a choking hazard, so save them far from toddlers. I demonstrated exactly how to do them on Kare11 Sunrise News.
To make magic orbs, you’ll need
-unflavored gelatin or agar*
-cold vegetable oil in a high container. Cool oil in freezer or on ice for at the very least an hour, or till it is cloudy, however still liquid.
HINT: Orbs made through vinegar and also agar shrink much better than those made through gelatin (see floating orb recipe below!)
Standard fancy orbs:
1. Through adult supervision, dissolve 5 packets unflavored gelatin or 2 Tbs. Agar in 1 cup warm water. Add 2 tsp. Vinegar. Microwave and also stir until completely dissolved.
2. Pour into smaller containers and include food coloring. As soon as cooler, however not solid, add the melted, fancy gelatin or agar to an empty glue container or squeeze bottle.
3. Drip gelatin or agar solution into the cold oil, a few drops in ~ a time therefore it creates into marble-sized orbs and sinks. Drip two colors with each other to make multi-colored orbs! enable to cool because that 30 seconds or so and retrieve with a slotted spoon or strainer. Rinse through water and repeat, re-chilling the oil as required until you have as plenty of orbs together you want.

4. Rinse orbs v water. Dry them the end by setup them top top a plate overnight if you want to see them shrink and also then re-hydrate them through water. Orbs can be preserved in a plastic bag in the refrigerator. (Keep away from small children, because they may be a choke hazard.)
To make floating orbs, monitor directions above, but make with 1 cup white vinegar and also 2 Tbs. Agar. They will sink and also float when added to water v a few tsp. That baking soda mixed in as the vinegar and baking soda reaction to type carbon dioxide gas.
To make color-changing orbs, dissolve 2 Tbs. Agar or 5 package unflavored gelatin in 1 cup red cabbage juice (magic potion) and follow directions for making orbs. Then drop lock in vinegar to clock them turn pink or in water comprise baking soda to watch them turn blue!
