Balloon pusher - sea tiger
It's not only known since Greta Thunberg that cruises are bad for the environment. These wooden boats have always been powered by pure balloon air and are already real classics.
< small> Information: Attention! Not suitable for children under 36 months due to small parts that can be swallowed. Age recommendation: from 8 years, since younger children can choke on balloons that are not inflated or burst. Adult supervision is required. Balloons that are not inflated or burst must be kept away from children. The balloon is made of natural rubber latex, which can cause allergies. Please use a pump to inflate.
