We'd always assumed that Kendall Jenner would be a pretty cool aunt, and her latest brilliant birthday gift for her niece North West is all the proof we need.

Kim Kardashian and Kanye West's eldest child turned four earlier this month and naturally was showered in an array of lavish gifts, Kardashian-style, including a tiny Pomeranian puppy (since named 'Sushi' after Kim put the decision to a vote on her Twitter account…) For the rest of her family, then, the question was surely: What to get the pre-schooler who has everything?

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 doubtless keep North occupied (and making plenty of mess) for hours.

Clearly impressed by her sister's choice of gift, Kim took to Snapchat to share it with her 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." The favorites in question? Bath Fizzies, Sticky Slime, Sugar Crystal Lollipops and Monster Marshmallows: all of which are hopefully coming to an episode of Keeping Up With the Kardashians soon…
