The exploding lunch bag!

Last week in Science, the Preps took part in a messy but super exciting experiment called The Exploding Lunch Bag.

What you will need:

  • 1/2 cup vinegar
  • Sandwich size ziplock bag
  • Bicarb soda
  • A tissue


As we listed each material the preps hypothesised what they believe may happen to the different materials once they are each placed in the lunch bag.

Monet – “I think it will turn into a liquid solution”

Jeannie – “I think it will explode”

Gabriel- “I think the bi-card soda will dissolve”

See below for the grand results!
