Did you shrink your students' leprechaun hats yet?? If so, you can swing on into MMMB to grab a freebie to get them thinking and writing! They will draw their hats before and after, then write how they think it happened! You will get the GREATEST ideas from them (albeit not necessarily to scientific!). It is so fun...then it is your choice if you choose to bring science into and explain how it was "likely" done. I opt to let them imagine and figure it out later in life....but it is entirely up to you, as well as the age of your students! Enjoy!
