Kim and Kanye's eldest child turned four earlier this month, and naturally was showered with an array of lavish gifts, including a tiny Pomeranian puppy (since named "Sushi" after Kim put the decision to a vote on her Twitter account).

Opting for the 'low key but clearly thoughtful' route, Kendall bought her niece a science craft book published by the Smithsonian museums. Titled Maker Lab: 28 Super Cool Projects, it's filled with the sort of DIY science experiments that will no doubt keep North occupied (and making a mess) for hours.

Clearly impressed by her sister's choice of gift, Kim shared it with her Snapchat followers, offering a close-up of the book while revealing, "[Kendall] picked out this science book, and then she picked out her four favorite projects inside of the science book and then packed each one with each of the ingredients."

They included Bath Fizzies, Sticky Slime, Sugar Crystal Lollipops, and Monster Marshmallows, all of which will hopefully appear on an upcoming episode of Keeping Up With the Kardashians!
