*by P***Y on 15 December 2020*

My son doesn't like candy (I know right? who doesn't like candy?!), so every year picking an advent calendar for him is a challenge. We have done the Thomas the train one (when he was 3), we have done Paw Patrol toys, Disney ones, but at 6, he is no longer interested in little "toys" anymore, and due to Covid, I did not have the chance to collect things to make my own advent calendar for him, so even though this product says it's for 8 and older, I decided to give it a try. My husband usually does it with him so I think it's perfect even though he can't quite read the instructions yet or do it by himself. It's their bonding time together (yes, give mama a break! and honestly I think my husband really enjoys it). We are 14 days into it, and while some of the experiments are okay, some are really fun. Each box after you opened it can be flipped and put back into the box and at the end of the 24 days will turn the board turn into a board game. Obviously we're not quite there yet, but so far I am very pleased with the experiments included. Each day's kit take about 2-5 minutes to complete so it's not like those science kit that get a little overwhelming. I would recommend others to start looking into buying around October though, which is around the time we purchased it. Otherwise I see the price of these advent calendars skyrocket around November. It's ridiculous. Overall I would recommend this to any family with a kid who likes science experiments (and since most things we just throw away at the end there is no hording of little toys that will never get played with again).
