This simple boat craft for kids is a perfect complement to water play, imaginative play and also explores the concept of sinking and floating.
(And is also perfect if your household is filled with voracious avocado eaters like ours!)
Painted avocado shells
The straws will form your mast. Make 3 cuts in the bottom of the straw to create a fan-like base.
Choose your “sails.” We folded a square piece of origami in half, to create triangles.
We then folded this triangle in half again to create a smaller triangle. Cut along the fold.
We taped our sail to the straw. You could also use a hole punch and punch a hole in the top and bottom of the sail and then thread the sail through.
Tape the 3 “legs” of the straw into the boat. (Using a hot glue gun would probably do the trick as well.)
We used bendy straws. Initially I thought that we could just tape the bent part of the straw into the avocado, but the mast didn’t always bear weight well in this scenario.
At this stage, you engage in a great trial and error process trying to find the point at which the mast will balance.
(I wasn’t actually anticipating this activity to take such a scientific turn- but lots of great discussion opportunities around buoyancy, sinking and floating.)
We discovered that you need to stick the mast slightly towards one end of the boat with the sail pointing towards the other end of the boat.
Fill a water play table or wading pool with water and sail your boats!
We had varying success with each boat.
We used Hass and Shepard avocados and discovered that the more bulbous nature of the Hass was more conducive to this activity.
(The random things you learn, hey? #mumlife.)
Excuse me now whilst I scour the fridge for other vegetables we can turn into modes of transport.
Are you any good at Science-y stuff? It’s definitely not my strong point!
