These are some fun and cheap gadgets that are unique each in their own way.
These are really fun when you het the hang of them.
The first is a small one that I recommended flying in doors.
It can fly four about 8 minutes before needing to be charged again. It also has a camera.
The second is also very fun and is about 5 times bigger than the first. I would recommended flying it outside and only flying once you get used to the controls.
The following are just fun cheap and random gift ideas.
Fan that plugs into your computer/ laptop
Small fridge that plugs into computer
