liquid candy concentrates are a suspension in a medium specifically for mixing with a specific carrier, which is great, except I’m experimenting to do something new by testing a different coating as a carrier.

Does anybody have a source in the US for the transparent pigments used in the high quality candy concentrates? The high quality ones are typically organic, semi transparent, and very small particle size pigments that have to be suspended.

if it matters, I’m specifically looking for amber, red, orange, and yellow.

Thank yall!

Hi All, I'm giving a science focused lecture on freediving and I want to do a section on the interesting technology and physics behind our freediving equipment. We don't use much, but the fine details will be fascinating to this audience of science and engineering professionals and enthusiasts. I already have my content for the effects on the body, biology, etc.

Looking for interesting information, visuals, videos, or contacts on subjects like, but not limited to:

• Bi-fins, monofins, unconventional swim equipment like the DARPA powerswim, Smith Engineering DOL-fin, and beyond.
• Hydrodynamics and computational fluid dynamics (CFD) diagrams
• Thrust coefficients
• Different stiffness gradients of fins (soft VS hard tips)
• Materials and fiber layups
• Unconventional and new/high-tech equipment (the new no-limit rigs look wild!)
• Weird experiments or anything else off-beat going on in freediving related to anything, not just equipment

If anybody has connections to composite fin companies, I would love an introduction!
