Finally, a shirt that brings atomic stability to your wardrobe! Our "Isotope You Not" design features a gleefully unstable portrait surrounded by electron shells that are more organized than your lab notebook. It's the perfect way to say "I'm positive about my protons" while keeping your neutrons neutral.

Like a radioactive atom seeking its ground state, this design radiates humor with a decay rate guaranteed to last longer than Carbon-14. The retro-style laughing face at the nucleus of the design proves that even atomic particles know a good chemistry joke when they split one.

Warning: May cause spontaneous reactions in chemistry labs. Side effects include uncontrollable urges to make particle physics puns and explain atomic theory to strangers.

Features:
More stable than your last relationship with a noble gas
Electron shells clearer than your understanding of quantum numbers
Guaranteed to get a reaction from other chemistry nerds
Half-life longer than your average study session
Atomic number: Awesome

Care Instructions:
Wash at atomic temperatures
Dry without quantum tunneling
Iron along electron orbital paths
Avoid strong nuclear forces in dryer
