RH803A – funny RC jumpmobile
My children get bored with radio-controlled cars in a day or two. This rubbish turned out to be more fun – it jumps (both from a running start and on the spot), it can easily jump onto the sofa. Completely insensitive to falls – bounces like a ball. In general, the children are happy. There was also a disadvantage. Important, but removable.
An autopsy, a short video of work and giblets and a little bit of necro-cinema
