Origin China
Dimensions 6.5 x 2 x 2 Inches
Material Glass, Secret Liquid

One of the most popular items in our Play Capsule, the glass hand boiler feels like something from an alchemist’s laboratory. The liquid in the glass sculpture has a very low specific heat which means that the warmth of your hand is enough to make it boil. Cup the lower bulb in your palm and the liquid seems to defy gravity, rising up and around the twisting glass tubes into the upper bulb and then erupting into a rolling boil. A very surprising and captivating science toy that almost feels like magic.

Shipping & Returns

Our products ship through a privately owned climate-controlled warehouse in San Diego, California.

We offer a variety of shipping methods from budget-friendly to price-doesn’t-matter. You can compare estimated costs and transit times once you begin the checkout process and enter your shipping address. Carrier options may vary based on your destination.

We strive to pack and ship all items within 24 hours of each order (Monday through Friday). However, we are a small team so during peak holiday season we kindly ask that you allow 3-5 days for your items to be sent on their way. Every box shipped from Art of Play is expertly packed by actual human beings (you can see their names written on your package slip). Everyone in our warehouse is paid a fair wage and treated with respect.

Return Policy

We will gladly offer a refund or store credit in exchange for any items returned within 30 days of the original order, as long as the items are still sealed in new condition. We cannot accept returns of opened or used items. Return shipping is the responsibility of the customer.
