Slime Advent Calendar 2026 - 24 Days of Non-Sticky Christmas Slime and Charms

Slime Advent Calendar: the calendar that doesn’t stick to anything

Most parents have banned slime at least once. It sticks to the table, the carpet and the dog. With this calendar, it’s allowed again. Behind the 24 doors are 12 Christmas slimes with their own names, such as Gingerbread Forest, Candy Cane Twist, Frozen Magic, Pinky Snowball, Christmas Mocha and more, with 12 days of charms, sprinkles and toppings in between to mix into them. The slime isn’t sticky, has a scent and comes in its own lidded pot, so it stays in the pot and doesn’t end up on your floor.

Slime today, charms tomorrow

One day there’s a pot of slime, and the next day there are the charms and sprinkles that go with it. This rhythm keeps a 9-year-old opening doors through Christmas Eve, instead of losing interest by day 5. Each slime has a different texture, such as butter, cloud, clear and glossy, as well as its own scent.

Who is it for?

Children aged 6 to 13 who are crazy about slime, and the parents who aren’t. It’s also for grandparents looking for something that isn’t chocolate, and for older children who say they’re too old for an advent calendar, until they open door one.

How it works

The calendar arrives ready to use in its own box. Open door one on 1 December, then one door each day until Christmas Eve. Put the slime back in the pot, put the lid on, and you’re done.
