Grab bag ideas...

Watergirl21

So for LO's 1st birthday, we are having some friends and family over for a BBQ and I thought since there are a lot of kids that we would do some sort of craft and grab bag.  Well I figured out the craft- but I don't know about the grab bag.  We are having a few 1 year olds, 1 2yrs, 1 3 yrs, 4 5yr old girls, a 7 yr old and and a 10 year old boy.  So far I bought some of those containers for blowing bubbles, and some plastic garden buckets and watering cans with some tools.  I think this will work for the kids up to 4 (will a 5 year old like this?)  but i don't know about the 7 and 10 year old.  It is mostly girls with the 10 and 2 year old being a boy.
