  • Must Have For Your Favorite Magician! Must Have For Your Favorite Magician!
I picked up this Advent set for my teen son, who’s obsessed with all things magic, and it has been a fantastic surprise. Each day’s item feels like a mini magical reveal—fun, clever, and just mysterious enough to keep him excited. He’s genuinely eager to open it every morning! The quality is great, the themed pieces are unique, and it’s been wonderful seeing him practice little tricks and show off new surprises each day. It’s the perfect mix of creativity and magical fun. If you have a teen boy who loves magic or enjoys a touch of wonder in his day, this Advent set is a perfect choice. Highly recommended! ... show more

  • Great kit to encourage the kids to get along before Christmas!
This has been a great way to countdown to Christmas and to get my boys interacting and working together daily. Each of my boys (ages 6, 10, and 11) choose an advent calendar each year and this one was selected by my 6 year old. He has been able to do most of the experiments with minimal help from his older brothers. Not every day is an experiment, some days are gems or stones. The included book tells you what each day holds so if you know you are going to have a busy morning you could have your kid go out of order and choose a gem on that day (this is what we do). There is also plenty of material to complete some of the experiments multiple times so the boys have taken the kit over to their grandparents to show them some of the experiments that they have already conducted at home. Overall, I would recommend this kit for any kids into science! ... show more

  • Best purchase for kids.
This set is truly one of the best gifts you can give to a child. It’s not just a toy, it’s an engaging learning experience that keeps kids entertained while introducing them to the wonders of science in a fun and interactive way. What makes this product stand out is how it combines magic tricks with real scientific principles. Children don’t just perform tricks; they learn the “why” behind them. This approach helps them naturally develop curiosity and a deeper interest in scientific knowledge. Instead of memorizing facts, they discover concepts through hands-on experimentation and play. It’s perfect for keeping kids engaged over multiple days, building anticipation and excitement as they move through each activity. The structure encourages consistent learning while still feeling like a fun daily surprise. ... show more

  • Advent, but Make It a Full-Time Job
As Thanksgiving approached, I was in the market for an Advent calendar for my boys. We had already exhausted most varieties, so when I spotted the National Geographic Mega Science Advent Calendar, the science educator in me was instantly sold. I imagined calm mornings with a quick, tidy experiment before rushing out to catch the bus. I hesitated only briefly at checkout. Was this too ambitious? I reread the description and reassured myself that some days were simply rocks, gems, or minerals. That seemed reasonable. I clicked purchase and spent the next few weeks eagerly awaiting December. The first few days were genuinely fun—new knowledge, excitement, curiosity. What I didn’t anticipate was a winter illness taking over our house, paired with ten school spirit days requiring coordinated outfits and enthusiasm I did not have. Somewhere along the way, I began actively hoping the next day would be a rock. Ideally several rocks in a row. Instead, National Geographic escalated. Some days now included two or three experiments. We were no longer pacing ourselves; we were rocketing toward the finale like a Fourth of July fireworks show that would not end. The final days before Christmas became a chaotic mix of gift wrapping, baking, shopping, and science experiments, interrupted only by a few merciful rock days. The final experiment, “Is That Gold?”, promised to “get messy” and required a frigid excavation outside of a rock I was certain would not be gold. This kit did not disappoint. By this point, the real reward was finally throwing the remains of this Advent calendar—and possibly part of my soul—into the trash and moving bravely into the new year. 5 stars, highly recommend ... show more

  • Great but beware of the book spoiling the days
Really good set of science and magic sets but buyer beware. All of the days are spoiled if the opener reads the book in the side. It has really neat stuff and great to do together but the whole experience can be ruined if they get the book out

  • Fun for all
This has been very fun so far! My 10 year old is the main one doing the experiments. This comes with excellent detailed instructions. So far all pieces are great quality. We have opened rose quartz and tigers eye crystals and they are indeed real. (I collect crystals so I can tell the difference.) It is easy to open each daily door. This is a great value for the money! It even comes with a pamphlet with extra experiments you can do. ... show more

  • Learning while enjoying anticipation Learning while enjoying anticipation
What a fun way to count down the days until Christmas. The Christmas story even talks about how a "new star appeared." A great lead into a solar discussion and fun space adventures. It's nice that there are things to do, not just a toy to open. It spreads the fun out for longer. Very colorful packaging. You can trust a name brand to put out quality items. Got it just in time for the beginning of December. ... show more

  • Neat but a little biased
This was so much fun and my son loved it. Is also incorporated some science in so it was a good learning experience for him as well. My only complaint is that on one of the days you get a pretend thumb (to pretend like you’re pulling your thumb off). The color was light beige. For kids that have black or brown skin this will not work (obviously it looks fake no matter what but that’s not the point). It seems like the producer of this product just assumed it would only be lighter skinned kids using it (or just didn’t care) which is ridiculous. Offer color options or take it out completely. My child has lighter skin that is closer to the color of the fake thumb so it worked for us but I could see how others would be very disappointed to find this. ... show more
