Happy International Submarine Day! (Yep, that’s a real thing, March 17th.) Here’s an easy submarine that kids can make- best of all, you only need 4 things that are in almost every home to get hours of play from it.

You need:

-a paperclip

-a pen cap

-Blue Tack (or whatever you call that blue stuff that sticks posters to the wall)

-a plastic water bottle – I know, environmental sinning, but your local recycling place probably has one you can use if you don’t want to buy one.

Here’s the video we learned it from:

This was really entertaining, but I wanted to make sure that D8 learned something from it too. We got out The Way Things Work by David McCauley and looked at the page that explained more about ballast tanks, hydroplanes and compressed air and how they’re used to adjust the level of the sub. D speculated that the water entering the pen cap works like a ballast tank, and that squeezing increased the pressure of the water drawing his “sub” down.  Not one hundred percent accurate but enough to show that he has a grasp on the subject!

Why yes, he does need a haircut. There are eyes under there somewhere.
