Sip Your Mass Balances


  • Margot Vigeant Bucknell University
  • Seth Pletcher



I’d like to introduce a co-author for this column - everyone, say hi to Seth, a 2023 graduate of our program! He’s here because he did a nifty undergraduate project with my colleague Jim Maneval that I want to share with you. It makes a great example for students pondering mass balances and the bigger picture of where our raw materials come from.
