Valentine's "cards" from our house

Each year, I try to outdo myself on the Valentine's Rylie takes to school for her classmates. Here are this years:

I am in love with these. And they are very simple to create. All you  need is:    

 plastic easter eggs, construction paper, a pen, hot glue gun, and scissors (not shown). My daughter then made paper hearts, cut them out, and wrote "have an 'egg'citing valentine's day" on each.  We then hot glued each one to an egg so it could still open (like this:)

                                                                                 
All we have to do is add the "flubber" (or slime) we made for her science project inside each and she will have "egg"cellent Valentine's for everyone
