There is so much material to get inspiration from. Look in your chem lab. You'll see lots of equipment that is ripe for annotating a chat up line and cracking jokes. Fx. bunsen burner, tongs, thermometer, funnel, test tube, rubber corks, scoopula. The list goes on.
The Holy Grail is of course the periodic table with all its elements. With a little creativity you will be able to combine them to come up with your very own unique pick up line.
If you come up with a good chem line, tweet it to us at @PickUpLine_Guru with hashtag #chemistry. We'll publish the best ones on here.
