Lovely glass, great quality, very stylish. Bought as a gift. Had bought one before, decided to get three more as gifts. They are lovely as the designs are so different, and can be chosen for an individual.

It is a very nice glass, with a very original design, at a reasonable price.

Solar System Whiskey Glass

Nice item, good quality and appreciated the packaging and ethos behind it. Made a lovely, much appreciated present.

The Chemistry of Whiskey Glass is beautiful! I opted for the gold writing and it looks very classy and I cannot wait to give it as a gift this year!! The glass was packaged well, no concerns with it being chipped or broken and it arrived faster than expected. I also found a few other items I am looking forward to purchasing from Cognitive Surplus and will absolutely be a customer for the long-haul.

The walls are too thin, very fragile

We gave this to my EE father for Christmas and he FLIPPED OUT! He LOVES it - and it's truly a beautiful glass.

I purchased this as a gift, and was very pleased by the appearance of the glass. The skulls are nicely rendered and several different hominins are represented. Nice job.

I haven't used this, it was purchased as a Christmas gift for a chemist who loves whiskey. I'm sure he will love it.

We got this for my husband for Father's Day, and he loves it. He is a whiskey and bourbon drinker and he likes the weight and the design.

Yes, we have enjoyed them. But I think as drinking glasses they feel a bit fragile, as if one wrong move and they'd crack. I love the idea of 'equations that changed the world,' but I also think the type font is too small. Part of the joy is to read the equations and marvel at them. (One of my children is an electrical engineer and he explains what many of them actually mean.) But they're hard to read at that size. Also, I ordered gold. Bad idea. Should be black. If black had been available, I completely missed that option.

bought two glasses and love the gold design, light and are great!

Can’t wait to receive the glass that you report as delivered.

Love these glasses. Not only are the fun to look at, but somehow make my whiskey taste better.

I absolutely love this glass. The design is so cute and the cup is great quality. I want 20.

Great surprise for my science loving husband!

Not everything in science needs to be serious. A bit of fun and a wee dram of bourbon helps one understand chemical bonds.

Yes!!! This cup is amazing, and we’ve washed it several times and the decal hasn’t come off at all.

It is everything I wanted it to be. It was even a little bit wider than my standard whiskey glasses. Dishwasher safe is a major plus.

Quaintly product and a fun conversation piece.

I bought this glass as a birthday gift for my husband, and he loves it. The wide mouth is particularly good for large ice blocks or spheres, making it great for cocktails or for bourbon on the rocks. He already wants more glasses like this!

Brings back lots of memories, good and not so good! 😬

The experience of drinking from these glasses is intoxicating. The half-life of a beverage in these glasses appears to be decreasing on a geometric scale. Perhaps there is a relationship? What is your theory there Darwin?

We love our glasses. Great design, solid quality, nice shape and weight. We have run them through the dishwasher without problem. They are fun visually and the gold is very attractive.

Have gotten a lot of compliments from both nerds and non/nerds alike.

Had a small issue with shiipping but was not the fault of Cognitive Surplus. They were more than helpful finding out where the package was!

The only problem I’ve seen so far is that one of the glasses started to flake off after a wash.

My math teacher son loved it!

Love this glass, it's a go-to for me now. Well designed and put together, fantastic theme.

I've enjoyed drinking from it. I like the chemical structures on it.

BEAUTIFUL GLASS! THANK YOU!!!!

BEAUTIFUL GLASS! THANK YOU!!!!

This was perfect for my sister who is a paramedic and appreciates these kinds of nerdy details.
