My littlest man turned three today. He's had high expectations for his birthday ever since his big brothers had their birthdays in January. What he really wanted most was to launch some model rockets. He's been asking for that for weeks. I wasn't too keen on shelling out cash for a one-use rocket and launch system, at least not for a three year old, so it was a good thing we remembered the water rocket we built last summer and stored away in the garage.
We used the plans from one of our all-time favorite project books, Howtoons. You can find more information on building your own at the Howtoons website.
In the meantime, check out how high our rocket flew:
