Hydro Dynamic Challenge
Intro
My class is working on cleaning the oceans, creeks, and rivers of plastic and garbage. Thanks to COVID 19 we have to stay at home so we do all our work while at home! By staying home I was able to find more research links for you to look at.
Idea
I thought of making an invention that can filter water and clean it up but you can't drink out of it. I got the idea from the invention of the LifeStraw because it has a filter that removes about 99.9999% bacteria and it also removes the chance of getting Guinea worm and Giardia. Here is a list of things that LifeStraw can filter: Poop water, toilet water, mud puddle, pond water, clear water, and spit water, things that Life Straw can't filter: Pee, Saltwater, Sprite, Pepsi, Mountain Dew, Lemonade, Chocolate milk, and probably Slurpy juice. Sorry if I weird you out!
What I Will Make My Filter\Straw Out Of
I will use a lot of fuzzy pipe cleaners for a filter and a sheet of plastic to wrap around the filter. I will need to cut the pipe cleaners in half to make the filter bigger. In my estimate, I think it will filter at least 80.6% of the water.This is a photo of my invention.

Anya, Thank you for a great explanation of your LifeStraw filtration project! I like seeing the photo and appreciate that you shared your sources for gathering ideas.
ReplyDeleteA quick factoid: Water from toilets is called "black" water, and water from showers and sinks is called "grey" water! Plumbers and people with campers and trailers use these terms.
Do you have some photos of the results of your straw filtration? How did the liquids change? I thought it was interesting that you tried all those beverages!
Thanks for sharing this! ~LizQ
