Some atoms decay quietly. Others buy a convertible and speed off into existential uncertainty.

This T-shirt captures the latter.

Whether you're a decaying isotope or just a human realizing time moves in one direction, this shirt hits that perfect fusion of physics humor and personal spiral.

Made for scientists, students, or anyone who’s ever made a questionable decision halfway through their timeline, this tee says what the lab coat won’t:
You’re still reacting, just not the way you used to.

Slip it on. Floor it. Decay in style.

• 100% combed and ring-spun cotton (Heather colors contain polyester)
• Fabric weight: 4.2 oz./yd.² (142 g/m²)
• Pre-shrunk fabric
• Side-seamed construction
• Shoulder-to-shoulder taping


This product is made especially for you as soon as you place an order, which is why it takes us a bit longer to deliver it to you. Making products on demand instead of in bulk helps reduce overproduction, so thank you for making thoughtful purchasing decisions!
