Then I had 2 volunteers confront each various other to show just how to kiss. By now, hearts were beating pretty fast! The boy starts by politely saying, "May I kiss you?" The girl politely responds by saying, "Yes, let"s kiss."Once I recognize the course is more than a little nervous, I hand also my volunteers a test tube and show them how to "kiss" in science for this experiment. There are audible sighs of relief!A KISS= Use a pipette to carry the clear liquid from your test tube to the other person"s test tube. They use a pipette to deliver some of their clear liquid from their test tube to yours. The exchange is dubbed a "kiss".
