## Description

desertcart.com: The Unemployed Philosophers Guild Heat Changing Constellation Mug - Add Coffee or Tea and 11 Constellations Appear - Comes in a Fun Gift Box : Home & Kitchen

Review: A Magical Mug for Stargazers!!! - This heat-changing constellation mug is absolutely fantastic! The moment you pour in a hot beverage, the stars come to life, revealing 11 beautiful constellations—it’s like having a little bit of the night sky right in your hands. The transformation is smooth and happens quickly, adding a fun and mesmerizing touch to my morning coffee routine. The quality is great—the mug has a solid feel, and the print is crisp and well-detailed. It also comes in a fun and well-designed gift box, making it a perfect present for astronomy lovers, science geeks, or anyone who enjoys unique mugs. One thing to note: since it’s a heat-sensitive design, it’s best to hand wash to preserve the magic for as long as possible. But honestly, that’s a small trade-off Love it!!!!!
Review: I absolutely love it! - Anthony Wesley 2/9/2018 desertcart Product Review: Color-Changing Mug Recently, I purchased this color-changing constellation mug from desertcart. I absolutely love it!. I decided to buy this mug for my beautiful girlfriend, who loves to look at stars every time we walk outside. It was part of a Christmas gift for her. I am so happy I bought it. I would definitely rate this product 5 out of 5 stars. Overall: To evaluate this product, I used simple criteria. One: the insulation of the mug. With this specific mug, I realized that it was a great insulator of heat, keeping my girlfriend’s coffee warmer for a longer amount of time than her average $3 mugs from Walmart. Appearance: Another criteria of judging I used was the overall appearance of the mug. This specific mug aside from it’s amazing color changing qualities, has a very smooth and shiny seal all over it. Making the mug easy to clean and easy to hold. When you first see the mug, it looks plain black and has stars all over it, even the handle. When you put hot liquid in the mug, (ie: coffee, hot chocolate, tea..) the entire mug changes color to let the owner see constellations clearly outlined all around the mug! The effect of the color-change is extremely fascinating overall. Functionality: It totally brings the mug to life in a fun way. Using this mug makes waking up early for class or work an even better experience as it wakes you up and reminds you of something amazing, the stars and constellations. As the liquid cools down again, the mug changes back to a plain black color, making it also reusable. The negatives about this product are that the handle of the star mug does not change color, but scientifically it makes sense why it wouldn't. The mug also is preferred to be hand washed only. I understand why it is not machine washable because it is so sensitive to heat, but it does make it a little more cumbersome to clean. Utilization: Lastly, I think this mug is perfect for those who live in cold weather (and enjoy hot drinks), or college students (who are fueled on coffee). This mug would even be perfect for learning children as when the constellations appear they also have names to go along with them so they understand. There are also nontraditional ways yo use this mug. I have commonly used this mug for the consumption of ice cream and it works perfectly when I also want to cool off on a hot day. My girlfriend drinks coffee at least 5 times per week, and she uses this mug as often as she can! I strongly recommend purchasing this mug!
