Want to conduct your own simple science experiments at home? Here we have a microplastic sampler that allows you to collect and separate out microplastic of various sizes from the sea.
How it works:
By stacking filters with different mesh sizes on top of eachother, we can collect microplastics of different sizes. The filter stack is lowered into the sea using a rope. The weighted end of the filter stack allows it to sink straight down. The cone end of the filter stack directs water away from the filters as its lowered into the sea, so that we are only allowing water to pass through the filter stack as its lifted out of the sea.
You can decide what size of microplastics you wan to look for by changing the material used for the filter. You can experiment with different materials e.g. tea bags, coffee filters, face coverings, tights etc. You can also stack as many different filters together as you like.
Assembly Instructions:
*Note: take care when working near the water. Always be mindful of ropes and trip hazards
