It’s lab day! You organize all your materials and chemicals onto your lab bench and figure that it couldn’t hurt to get yourself a snack and a drink before you start doing all that hard work. You pull out a few granola bars and start guzzling them down with an ice cold Gatorade. Ahhh.So refreshing! Suddenly,you notice some eyes on you... and... and... you think to yourself “should I have brought enough to share?” Do I have something on my face? WHY could all these people be looking at you?
