Does Gum Lose Mass When You Chew It?

I believe the gum will gain mass this is because the gum will absorb the saliva in you mouth and make it bigger.

MATERIALS:
Gum(orbit gum)
Analiysis page
Mouth
Scale
Clock or timer

Buy or steal three pieces of gum from store.
Weigh one piece of gum on a digital or regular scale
Put one piece of gum in open mouth
Chew concecutivly for one minute
Spit gum out on wax paper
Weigh the gum on the wax paper on the scale
Write down in grams your result
Repeat steps 3-7 three more times (with same gum)
Record your data on your analasis page rating the texture and taste through out your chewing. Repeat everything above 1-9 with a diferent piece of gum. Repeat steps 1-9 again one last time with different stick of gum . DONE!!!
