The Spider-Man pointing meme gets a chemistry twist that's actually scientifically accurate. Pure metallic sodium will literally explode on contact with water, while sodium in compounds (like table salt, NaCl) is essential for life. Similarly, metallic lead is relatively inert, but lead compounds are notoriously toxic. This meme beautifully captures how elements behave completely differently depending on their form—something first-year chemistry students discover right after they stop setting things on fire for fun.
