My daughter loved it!

She's 8, and loves science. She's said "mom, this looks like something for a scientist!" I said "well, you are a scientist!" She was so happy!

Thirst for Knowledge

Nothing quenches my thirst like reviewing my geochronology while imbibing liquids. And when you’re in the mood for just a Cretaceous amount of beer, an ordinary vessel will leave you guessing, and sad. No such sadness with the Core Sample Tumbler Glass.

I love how the cup honestly hints that we’re in the anthropoceane and we need to do something about climate change

Amazing! The quality and detail are even better than I expected. These are so fun, the perfect balance of cute and nerdy. Even the packaging was well designed.
