But be careful -- too long and all of the liquid gets gellified. If you have any of these health problems: Breathing problems, high calcium levels, or low calcium … In my last column, I explained the odd phenomenon of spherification, where two chemicals in water combine to form a gel that creates a sphere of water, making an edible water bottle.
In the Gooey Slime experiment, kids make a rubbery polymer called Gooey Slime using two chemicals PVA and Borax. ����'xMfTp�b�Ԛ=esԊ��ڃ�d]jbR�pH����zxrg�f:2 Sodium Carbonate or Sodium Chloride (table salt) - Yellow. 0000002139 00000 n Larger spheres forming in the alginate solution during reverse spherification. If the small spheres are too fragile, or you are trying to make larger spheres, leave them in the calcium chloride mix for longer, as the longer they are in there, the thicker the gel coating will become. 0000001116 00000 n 0000008287 00000 n
Instead of adding alginate to the liquid to be spherified, we add the calcium ions to the liquid, and then put this into an alginate bath. 0000004913 00000 n 1 -Dissolve 0.5 gram (0.02 oz.) 3 - Use a spoon or scoop to measure out as much of the calcium-infused mix as you want in each sphere.
I found the easiest way to do this was to use a small eyedropper, but you can use a small spoon or a straw. We will use this to rinse off the finished spheres. Do not get on skin or in eyes. 444 0 obj <> endobj xref 444 41 0000000016 00000 n It isn't difficult to do. 0000015817 00000 n Mix it and keep it for 3 days. of calcium chloride in water, preferably distilled. This takes some practice, but you want to get all of the mix into the alginate as quickly as you can, so it doesn't spread or flow.
Keep it for 5 hours. This is the hardest part of the process, as the alginate sometimes doesn't want to dissolve. Empty the Calcium Chloride test tube in the bowl and mix it. 0000011624 00000 n trailer <]/Prev 178431/XRefStm 1795>> startxref 0 %%EOF 484 0 obj <>stream Heat evolved is significant. In my next column, I'll experiment with a range of drinks and liquids, looking at what effect the chemistry of various foods has on the process.

The worms form in the worm slime experiment when Sodium Alginate is squirted into the Calcium Chloride solution.
In this experiment, kids make a worm like long chained polymer using different chemicals: Sodium Alginate and Calcium Chloride. If you are allergic to calcium chloride; any part of calcium chloride; or any other drugs, foods, or substances.
