Throwing water to test a groups den

This morning the whole school completed their final den building session. They were put in groups across the whole school from reception to year 6. Their task was to build a strong structure with covering to stand the test of a leaf blower and buckets of water being poured over. 
 

Some were successful with these missions having a water tight den that stood the test, where others didn't quite stand the test and ended up a little bit wet.
