Combining Puppy Theme And Mad Science Theme - Any Ideas?

by Karla

My soon to be 5 year old daughter wants to have a puppy party theme.

We are going to donate to a local animal shelter instead of gifts and give the kids stuffed puppies and have them make little tie fleece blankets for their puppies.

We recently received a gift certificate for her to have a mad science birthday party where they learn cool science experiments.

I am having a hard time coming up with ideas to combine the 2 themes.

I was thinking about maybe calling it "Puppies and Potions" birthday party. I don't know--any ideas would be appreciated for everything:
Invitations, activities, cake, food, drink, etc.

Thanks!
