    • A brilliant way to count down to Christmas! ✨🔬🦖
Style: Glow in the Dark Advent
This Glow in the Dark Advent Calendar really lit up our holiday season—literally and figuratively! Each day was like unwrapping a tiny science lab, packed with fun experiments and glowing surprises that had my kids saying, “Can we open tomorrow’s box now?!” by 9 AM. From fizzing reactions to glow-in-the-dark creatures, it’s the perfect mix of STEM and Santa. It’s educational, but shhh—don’t tell the kids. They just think it’s super cool. ✅ 24 hands-on activities ✅ Glows = extra wow factor ✅ Educational and fun (teacher-approved!) ✅ Kept my kids entertained without screen time 👏 If you're looking to add some chemical reaction to your holiday excitement, this advent calendar is pure Christmas magic in a box. ... show more

    • Excellent gift
Style: Magic Advent
Bought for my daughter last December and it was a big hit!! She couldn’t wait to get home from school each day to open her next window. Sometimes she even woke up early to do it before school! She would spend time learning the tricks and loved to show them off to people. It was very entertaining! This was such a great gift for a great price. I love advent calendars but don’t always want to give candy so this is perfect. ... show more

    • Great for my tween!
Style: Science Advent
This was perfect for my tween son. Full of daily science experiments that didn’t require significant time or supplies. He could follow the directions independently and loved the variety.
Reviewed in the United States on January 2, 2025 by This is the perfect size to fit in my traveler’s notebook. I love the weekly spread with extra room for to-do lists and journaling.
    • So much fun

    • Lovely Advent Magic Calendar
Style: Magic Advent
I think out of all the advent calendar boxes we've purchased, this was one of the best ones! Each daily magic trick has a video that demonstrates how to perform the trick. My 8 year old really enjoyed it, pretty difficult for my 4 year old, but he still enjoyed the props. I would definitely buy this one again! ... show more

    • Disappointed at missing items
Style: Glow in the Dark Advent
This calendar so far has a nice variety of surprises each day for my toddler but sadly we are missing a couple ingredients and materials needed for some science experiments. It also, doesnt come with instructions to perform the experiments. I have to Google to attempt then realize im missing pieces, that's the only thing I would change is add a manual and make sure all pieces are in each box. ... show more
