For party favors, the guests were able to take home samples of all the experiments they’d made (green slime, fake snow, etc.), so we didn’t really need to come up with anything else. But because Maude is a maker, we decoupaged mini-clipboards as well, filled them with graph paper and tied on a green pen. [Edit: I heard about this cute idea from my friend Megan. Thanks for the inspiration, Megan!]

brought white favor bags as part of the Science Explorers of NY party package. We added these green circles — attached with double-sided tape — to tie them into our party theme. They say: Thank you for coming to Maude’s Young Einstein party. Yay for cool science!

Here’s a link to a post about the party activities.
