Introduction: Thermal Coaster

In the cold seasons, we often want something hot to drink such as; coffee, a tea, a hot chocolate. Maybe, everyone would like to remain hot. However, it gradually gets cold.

The thermal coaster we will introduce has a heater to keep drinks hot, so you can enjoy hot drinks for a long time.

In addition, it’s very compact and you can make it easily.

Step 1: Materials

・Stainless steel bowl

・Wire basket

・Glue gun




We can get these easily and cheaply.

Step 2: Obtain a Heater

Disassemble the glue gun using a screwdriver and take out the heater within the glue gun.

Step 3: Drill Holes in the Stainless Steel Bowl

Drill five holes in the bottom of the stainless steel bowl. These holes have two roles. One is to pass wires, and the other is to conduct heat to the outside.

Step 4: Assemble

Attach the stainless steel bowl and the heater to the bottom of the wire basket using wires through the holes. (Caution: Close both surface tightly.)

Step 5: Warm Your Drink

When you plug it into an outlet, the heater gets warm, and you can enjoy hot drinks all the time! Please turn it off after you finish your beverage.
