Weirdly brown sugar boiled till hard is nearly perfect.

LiF, SrF2, or BeF2

I have no idea where to start or which rules need to be used. Any help would be greatly appreciated!

Thanks for your quick reply.  Being sticky is exactly what the rosin is there to do.  It's possible to use synthetic hair if the rosin doesn't suit horsehair.  Have you any suggestions?  A child's sticky sweet (glucose syrup) did a not too bad a job.  White sugar boiled till it would harden did nothing - the bow slid all over the place.

What I need is a water soluble adhesive that doesn't completely set.  The designer of one non-allergenic rosin used a medical adhesive for his base but that's no good to me as it's not water soluble.

I doubt it will work - when it gets humid sugar will start absorbing water and horse hair (or whatever they use now) will get sticky, that's exactly opposite of what the rosin is designed to do, no?

Think hard candy left in the open.

Hi folks.  I don't know if this is the right place but I'm trying to develop a water soluble violin rosin - all on the market are resin  or synthetic resin based.   Not sure where to start. I've tried boiling sugar till it sets hard.  Kinda works but not too well.  Any ideas?  Thanks.

To make methanol from sunlight and compound like CO2 seems exciting and important now when we need alternatives for fossil fuels, I know many are working in this area.

Undergrad research opportunity is allowing me to pick my own research topic (Chemistry specific) and design my own experiment for the next ~2 years

Help me brainstorm ideas?

These can be specific or broad strokes- something that seems interesting to you

**not looking for someone to put together my research project— I’m here for ideas that I can study to decide my final project direction 🙏🏼
