BC of marshmallow ?

My daughter teaches high school physics and we were haveing a discussion about ballistics...
One of the labs they do in class involves a marshmellow launcher. The lab requires the student to predetermine the flight of the projectile. They actually do have some kind of photo sensor to determine velocity...
Any body got any idea about the ballistic co efficient of a marsh mellow?
Thanks

Miniature, standard, or the new big ones...flavored? Your daughter is a physics teacher, seems it would be an easy question for her.

No flavors..
Miniature in size. They can calculate the force from a picket fence falling but BC isn't some thing they normally discuss...kinda like the term "launcher". In my day we called those something else.

canvasbk,

No, not with any sort of relevance. To begin, you'd need a "standard" marshmellow to form the basis of that table. Not being facetious here, but there's simply too much difference between a marshmellow and G1 projectile (or any other "Standard" projectile) for there to be any sort of comparison between the two.

Most HS physics doesnt take air resistance into account, only gravity. You sure they are taking into account the atmosphere.

What about the sectional density?
