Having constructed the boats a few weeks ago, (and done lots of other activities in the mean time – flag games in the woods, a “What 3 word” challenge etc. – it was time to try out the boats, and see if they would float. Each boat was placed into the water, and then 280g bags of flour and sugar were added as weights, to see whose would take the most. Some were limited by their size, some by the fact water seeped through the cracks, and some were a bit top-heavy. However some went all the way, and held all 7 weights!
