I almost forgot to tell you.

DONT EAT POWDERED EGGS!!! Dont subject 10 yr olds to powedered eggs either.

We made these things called Banana Boats. Holy cow.

1 banana
a few little mini choc chips
4 little mini marshmellows
1 12"square of tinfoil.

Slice banana up the side, (DONT PEEL BANANANANA) one side only, try to make it the side that would be up if u just set it down. Shove choc chips and shmellows in there too. Wrap up with tinfoil. put on hot coals.
Wait for the smell - the yummy gooey goodness smell. They are done in maybe 2 min - depending on your coals tho.
DONT BURN yourself either!

These are bringing back so many memories. I dont know if you will be able to use any of these, but when I was 7,8,9,10 etc I love love loved these ideas. They were so much fun, and so interactive. When your younger you just like to get right in there!
