How to Make a Body Centered Cubic Crystal Structure Model Out of Food

When learning crystalline structures on an atomic level, using food to make physical models is an easy and delicious way to supplement your studying and visualize these on a theoretical level!


  • Image titled Ingredients 13
  • Small pretzel sticks
  • Chocolate truffle balls (The Lindor brand works nicely.)


  1. Image titled Step2 41
    Purchase pretzels and chocolate truffles. You will need about 10-15 pretzels and 9 chocolate balls.

  • Be careful when using the drill, use the lowest speed setting possible when drilling into the chocolate balls.
  • Melted chocolate, when hot enough, can cause burns, use care when handling it.

Things You'll Need
