Eons pass in seconds!

At Vat19.com, we have a serious infatuation with dinosaurs. Next to owning a life-size Voltron, seeing a T-Rex brought back from extinction via some crazy Jurassic Park-esque "science" would be just about the coolest thing ever.

Thus, the Disappearing Dinosaur Mug pretty much had us at "Yo," (check out this heat change mug). Simply add some hot coffee and within a few seconds the dinosaurs on this mug transform into fossils. Sweet.

Colorful artwork morphs into fossil remains

The Disappearing Dinosaur Mug features three dinos. In addition to the Tyrannosaurus Rex, there's a sauropod (Brachiosaurus), and a Deinonychus (from the same family as the Velociraptor). Add a hot liquid and the prehistoric landscape disappears and morphs into a museum exhibit.

Frequently Asked Questions

Question: Can you drink tea with it?

Answer: How fortuitous that you ask! Yes, you can absolutely drink tea with it. You may want to check out our Tea-Rex mug as well.

Question: Shouldn't the Deinonychus be shown with feathers?

Answer: Yeah, we read that Wikipedia article, too. There is no definitive answer, but it is likely that it had feathers. Perhaps it lost them all due to the utter shock of having a 40-foot-long T. rex ready to rip its head off.

Question:  So... hot beverages made the dinosaurs go extinct?

Answer: Sure! It's as good of a theory as any, right?

Question: Is it dishwasher safe?

Answer: No. The high temperatures of the dishwasher could damage the heat-sensitive glaze.

Question: Is there a downloadable user manual for this mug?

Answer: Not currently, but here are some tips for operating your Disappearing Dinosaur Mug. Take your hand and place it on top of the mug. Press firmly. If you are able to work your hand inside the mug, then this is the end into which you should pour your refreshment.

Question: How long does it take for the dinosaurs to go "extinct"?

Answer: That depends on the temperature of the liquid. Near-boiling water can cause the image to turn in as little as 15-20 seconds. Hot, yet still sippable beverages, will take 45-50 seconds to transform the image. Once the heated liquid is removed, it can take about 5 minutes for the image to revert to its original form.
