I thought everyone already knew. Liquid paper was discovered in 1921 by Hieronymus W. Bunsen, then 22 years old, while playing with his new invention, the bunsen burner. He happened to hit on just the right conditions for paper to melt (rag-based paper only, doesn’t work with most modern paper). It’s the truth: accept no substitutes.
[This is, I should mention in case any of you slept through humor class, a joke. I’ve read that liquid paper was actually invented by Bette Nesmith Graham. Paint was invented a long time ago, but apparently new uses are still being found.]
