Scientists and astronauts frequently take what’s called a “core sample” of objects like rocks and trees to gather various kinds of information about them. For instance, you could find out how old a meteor is and what it’s made of by drilling into its surface and analyzing the core sample. These Peel ‘N’ Stick adhesive postcards allow you to become a scientist of your trip to Thailand or grandma’s house. Simply peel off the protective covering and swab the postcard on your vacation to collect a sample for family and loved ones. Want your cousin to know exactly what the sidewalk at Disneyland smells like? Swab away! Additionally, a little-known fact about scientists is their overwhelming lust for scrapbooking. These adhesive postcard are perfect for creating collages of foreign money, bus passes, hospital wrist bands—whatever two-dimensional objects characterize your trip. Peel, stick, and make your adventures known to the world!
