My son did an interesting experiment with a can of soda.
I don't understand the result he got but here's what he saw:
Any ideas what effect we're observing?
I'm surprised that the CO2 lost from a can going flat would have sufficient mass to cause any effect, and I definitely don't know why it would go UP in mass.
- Weigh the can before opening.
- Open the can and weigh it again.
- Wait a while (for the soda to go flat) and weigh it again
I don't understand the result he got but here's what he saw:
- Immediately after opening the soda, the weight of the can (and soda) went up. (0.2g)
- Once the soda went flat, the weight went had gone down (after one hour) (0.2g)
