This disguise motivates children to play and romp. Together with a laundry basket as a boat, the diving expedition can start quickly. All you need for this is a diving goggles or a snorkel, dark clothes, gloves, a dark cap and possibly a dark scarf. Maybe you also have fins.
A backpack with two empty water bottles serves here as diving bottles. Let yourself be inspired for the carnival party / carnival or for a children's birthday party on the topic of water.
First look for the materials and clothes together.
Then put the empty bottles in the backpack. Just leave it open above so that the bottles look out a bit.
Now have fun dressing up and playing.
Tip: In addition, a laundry basket stimulates a lot to play. Pull the children with the laundry basket or push them. In between, let them jump from the boat into the water, i.e. from the basket.
