Amphibious Bottle

The Amphibious Bottle rolls by rubber band power over water, tub, pool, puddles, lakes.

Just roll it away on the ground like a bowling ball to wind it up.

Step 1: Make first hole

Picture of Make first hole
Use a 2 quart round plastic bottle.

Big 2 quart round Gatorade bottles work great.

Drill a hole in the center of the bottom of the bottle.

Any size drill you have handy from 1/4 inch to 1/8 inch is fine.

You can even use a soldering iron to melt a hole in the bottle.

Wear safety goggles.

Work on a proper workbench, not your kitchen counter like I did.

Step 2: Prepare the Cap

Using a pencil, marker, awl or nail, mark the approximate center of the bottle cap.

Put the cap back on the bottle and drill out the center.

Just like the last step you can also use a soldering iron to melt a hole in the cap.

Step 3: Build the Rubber Motor

Loop recycled rubber bands from your daily newspaper together to make a strong rubber motor longer than than the jug.

Wrap a stack of 15 pennies in reused and recyclable aluminum foil, and duct tape this weight to the center of the rubber motor.

Stick one end of the rubber motor through the cap hole.

Using a wire or string, pull the other end of the rubber motor through the bottom of the jug.



Step 4: Install the Motor

Screw the cap onto the jug.

Use toothpicks as cross-pieces on the jug cap and bottom to keep the rubber band from slipping back into the jug.

Adjust the two ends of the rubber motor so that the weight is centered from side to side and top to bottom.

You may have to pull the rubber band ends back and forth until this is right.

Now duct tape the rubber bands and toothpicks to the cap and bottom of the bottle.

Thanks it should be easy to improve on this simple design. Maybe paddles hot glued onto the sides?
hey that would be cool
what if you got a huge container and used lots of bungee cords and a seat and had a person act as a weight. now that would be cool.
thx for voting!...btw this is a cool idea

I thught these were called come-back- cans? I made one in science a while ago.
iectyx3c (author)  Speedmite5 years ago
You are right, comeback cans are a great science toy. This one uses a recycled plastic bottle so you can use it in the water too.

i made one of these out of a cofee can. probably not as good as this one though.

Your coffee can toy is probably BETTER than mine for hallways and floors. But this works great in pools, tubs and puddles :)

What does this actually do? Does it roll or something?
iectyx3c (author)  roofm5 years ago
It sure does - It is an amphibious vehicle - it drives in dirt, over water. It is super easy to build (and mod) with stuff you probably have around.
