I once saw a video that showed how gel capsules was being made with: a polymer solution, blue dye & soapy water.
The capsules formed as soon as the droplets hit the soapy water, creating a hard outer shell with a liquid core.
Is there anyone who can help me find out what polymer solution could be used, where to buy & if it's even possible to create such a thing at home. (we have a company that sells chemicals to users at home).
Thank you in advance for any help you can provide.
