I have had the Hack Pack subscription since the first year to entertain/ educate my grandchildren. Even though they are young for this subscription, ages 3-8, we really enjoy and learn a lot.

We watch Mark’s videos together then do the build. They do need a bit of help but they sit thru the whole process. What is amazing is how much they retain of the science behind the builds. When their parents come to pick them up, they get demonstrations and lectures on the science. It blows me away how great their dissections are.

Our builds are on a bookshelf and they get a lot use. The grands are very protective of their builds.
