Travel Jar Water Pump

Travel Jar Water Pump
I will describe how to build a small motored water pump with a travel jar instead of the accepted bottle cap method. This will bring a number of benefits, including easy accessibility for repairs and adjustments of the internal fan. It's relatively cheap, functions well with vinyl tubing and, err... looks great.

I once took a hobby mootor and sealed the vents with glue and ran it completely under water. it sat there and ran perfectly in a jar of water.

You could just cover it in hot glue as long as you don't get any inside.

Hey man great 'ible I was helping my girlfriends mom with transferring gas from her transmission broken truck to her out of gas van and it got to thinking of ways I could pump water. (I wouldn't risk has since there can always be a problem with electricity).

I had a few questions.
1) can this be done using a larger jar Mainly to fit a larger motor and fan.
2) if so could I just use the fan blades off an old computer fan?

You could pump petrol with it without the risk of fire if you immerse the whole thing in some sort of insulating oil (like baby oil) and draw out just the two lines.

Hmm sounds like a good idea. I was also thinking if using the motor farther from the actual chamber would work. Like adding a thing metal rod from the fan inside the pump, to the motor some few feet away.

There's this awesome cog wheel in diskus inhalers ( http://www.google.lk/imgres?q=diskus+inhaler&um=1&hl=en&biw=1280&bih=629&tbm=isch&tbnid=7nIIqMnzDhQgPM:&imgrefurl=http://www.securingpharma.com/40/articles/527.php&docid=Pv-Ayh18LJuO0M&w=596&h=400&ei=z0RRTsnyBMzMrQfY7KyJDw&zoom=1 ) that you can use as the turbine for this. I'll upload an image later if I find time.
