Use Legos to Build Your Own Motor-Controlled Mini Submarine
Need a little inspiration to create a mini-submarine? This video can help you do just that.
By the end, you'll be able to build your own little submarine made out of Lego pieces - pretty neat!
All you will need is a plastic jug, some waterproof tape, glue, Tupperware, a mini motor, and of course, Lego pieces.
The video offers a straightforward way of building the submarine, but as you'll see, it requires some patience, and a few trial and error tries may be needed, as the video maker demonstrates.
There's a little bit of re-wiring involved for the motor to work; so you'll have to pay close attention to the video. But it's all manageable as you'll see in the video.
And last but not least, you'll need to find a lake in which to test your mini-submarine. If you don't have a lake handy, a bathtub will most likely work as nicely!
In this video, you enjoy the bonus footage of the Lego submarine submerged in the lake and swimming past shoals of fish, moving in and around step ladders, and generally operating underwater successfully.
It may not be the sleekest looking piece of equipment, but it certainly works.
