Harry Potter Marauder’s Map Mug for a Little Morning Mischief

2

I solemnly swear I’m up to no good. I mean, who is ever on their best behavior before the first cup of coffee in the morning? Thankfully my heat changing Harry Potter Marauder’s Map mug is up for the challenge.

The Harry Potter heat changing mug uses a little bit of magic to make mornings more fun. When a hot beverage is added to the mug, the image on the outside turns from jet black to reveal the hidden Marauder’s Map design within. Mornings are always better with a little mischief.

Put down the wand and pick up the kettle for your heat changing Harry Potter Marauder’s Map mug!

Tempted as you may be to cast Aparecium, you won’t need to with this Harry Potter heat changing mug. Instead of magic, you only need to add a hot beverage to reveal the hidden secrets within.

This 11-ounce ceramic mug features a unique heat sensitive design on the outside. What appears to be a solid black mug reacts upon the addition of hot liquid.

Add in your coffee, tea, or hot chocolate and you’ll see the familiar steps of the Marauder’s Map begin to appear. In addition to the steps, Hogwarts map fragments and “I solemnly swear I’m up to no good” will appear. The opposite side of the mug has “Mischief Managed” appear as well.

Can you put a heat changing mug in the microwave?

While technically safe, it is not recommended to put a heat changing mug in the microwave.

It won’t cause any chemical reactions or the mug to shatter. However, it will break down the heat-changing properties of the finish early. Thus, putting your Harry Potter heat changing mug in the microwave will shorten its lifespan.

This applies to the dishwasher as well. While technically safe, hand washing is advised for the greatest enjoyment from your mug.
