Why are pill bottles, etc. that are supposedly "child proof" easier for children to stretch out than adults?

It is because children's minds, being brand new to the world, are open-minded and try multiple things adults wouldn't. A child would be creative and try out things while the developed would simply try one thing over and over again, which might come to nothing.
ha ha, that's true! I think it is because they are a short time ago plain determined. They will stop at nothing until their curiosity is jam-packed.
ANGRY AMERICAN,
THE VAST MAJORITY OF 'CHILD PROOF' ARE ACTUALLY MEANT TO BE "CHILD TAMPER-PROOF", BUT NO BOTTLE IS COMPLETELY CHILD PROOF. SOME BOTTLES ARE DIFFICULT TO OPEN FOR ADULTS WHO HAVE ARTHRITIS OR SOME OTHER WEAKNESS IN THEIR HANDS.
