Hi, my name is Viktor and sorry for my English.
What do you say, if your favorite drink turn into something resembling caviar? In this project we will transform a liquid into sphere that can be eaten with a spoon.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: How Does It All Work?
To make the caviar from the liquid you will need two main components:
- Sodium Alginate
- Calcium Chloride
Sodium Alginate is used in the food industry as an additive E401. It is used as a thickener and stabilizer.
Calcium Chloride is also a food additive called E509. The main application is curing agent in food products. It is a porous bits of white, readily soluble in water.
Of course, Sodium Alginate and Calcium Chloride are quite unusual components, but you can buy them in the online stores.
Step 2: Firstly, Let's Make the Caviar From the Tomato Juice
Mix 100 grams of the tomato juice and 1 gram of Sodium Alginate.
Here we need a mixer or blender. If mixing the powder of Sodium Alginate by spoon it will take a lot of time. The mixer will make it in just a few seconds.
Leave for 10 minutes, so that the powder is completely dissolved.
Step 3: Next, Make a Bath
Mix 5 grams of Calcium Chloride and 1 liter of water. I use plain water at room temperature. Calcium Chloride is readily soluble in water, so the mixer is not needed here.
Take the syringe with the maximum volume and fill the syringe of juice mixture with Sodium Alginate.
Place the syringe over the container with the bath and slowly push the plunger to get a small drop.
As soon as the juice hits the water, starts instant spherification.
It looks like a real caviar!
Wait a couple of minutes to harden the shell.
After that you need to use a sieve to get the caviar and rinse in plain water without Calcium Chloride.
The shell will harden in 15-20 minutes, so to get an explosive effect in the mouth, it is better to eat them immediately.
Step 6: I Made This Experiment With Other Products:
- Carrot Juice
- Apple juice
For the sake of science I tried everything. To be honest, it is very unusual taste to conventional products in spherical form.
If you still find Sodium Alginate and Calcium Chloride - be sure to try to do it yourself!

I hope you like it!
It should be noted that the additives E401 and E509 are allowed to use in most countries of the world as a safe, but subject to concentration in food. Permitted concentration per kilogram of product is not more than 20 grams of Sodium Alginate and up to 10 grams of Calcium Chloride.
