Unscrew the ablative heat shield (aka the bottom) of this capsule to open it, fill it with your favorite loose-leaf tea, reseal it, and drop it to the bottom of your mug. And the recovery doesn’t require a U.S. Navy vessel – just your fingers. Pull the capsule up using the chain with little astronaut serving as your counterweight, and your mission will be deemed successful in just a few short minutes.
