Make your own boat out of avocado to explore the concepts of floating and sinkingThis 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!)

Firstly, eat your avocado. (Too obvious?!)
Scrape all the flesh out and wash the inside of the avocado. We left ours to dry for 4 days.
Once dried out, paint the inside of your avocado.

What You Will Need

Origami paper
Straws
Tape
Scissors
Painted avocado shells

How to:

We then folded this triangle in half again to create a smaller triangle. Cut along the fold.
A fun (and nutritious) boat craft for kids to make, using avocados, to explore the concepts of floating and sinkingWe 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.

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.
Enjoy!

Are you any good at Science-y stuff? It’s definitely not my strong point!
