This one ties into our invention of the day as well! These are some plastic/paper eggs, I've never seen before, that my wife picked up for $1.99. $1.99 people! Pretty cool Easter invention for 2 bucks. We took sharpies to them for our family activity last night. Super easy. Though, we did eventually decid we liked using paint pens better. Still, way fun, and we have some crazy cool handmade eggs we will keep (and hide) from year to year. Success!
