ClassX Video Lessons Youtube Channel SmarterEveryDay Which Shape CUTS BEST? (Weed Eater Line at 100,000 Frames Per Second) – Smarter Every Day 238
Hi there! I’m Destin, and welcome to Smarter Every Day. Have you ever wondered why some weed eater lines work better than others? Today, we’re going to explore this by looking at different shapes of weed eater lines and see which one cuts grass the best. Let’s dive in!
First, let’s clear up some names. I call it a “weed eater,” but you might know it as a “string trimmer” or “weed whacker.” No matter what you call it, it’s the same tool used to trim grass and weeds in your yard.
When you’re shopping for a weed eater line, you’ll notice there are many choices. They come in different shapes and sizes, and each one can affect how well it cuts. Today, we’re going to use a super cool high-speed camera to see how these different lines work on grass.
In our garage, we set up a microscope to look closely at the shapes of different weed eater lines. We tested several types: a round line, a gray round line, a triangular line, a star pattern, a dull square, and a sharp square.
After testing, we noticed some interesting things:
We also talked to Robert, a local expert who uses weed eaters every day. He gave us some great tips and suggested weighing the lines to find out their linear density, which can help determine how well they cut.
After looking at all the results, here’s what we found:
I hope this helps you pick the right weed eater line for your yard. Thanks for joining me on Smarter Every Day!
Explore different shapes of weed eater lines by creating models using clay or playdough. Try to replicate the round, triangular, star, and square shapes. Discuss with your classmates how these shapes might affect the cutting ability of the line.
Imagine you have a high-speed camera. Draw a comic strip or storyboard that shows how different weed eater lines cut grass at high speeds. Use your imagination to depict the action and results of each shape cutting through grass.
Conduct a sound experiment by using different materials to simulate the noise levels of various weed eater lines. Use rubber bands, paper, and other materials to create sounds and discuss why some shapes might be quieter than others.
Learn about linear density by weighing different objects and calculating their density. Discuss how the density of a weed eater line might influence its cutting efficiency and durability.
Role-play an interview with a local gardening expert. One student can be the expert, and another can be the interviewer. Prepare questions about the best weed eater lines for different types of grass and discuss the expert’s recommendations.
Sure! Here’s a sanitized version of the transcript, with any informal language and unnecessary details removed for clarity:

My name is Destin, and this is Smarter Every Day. In a previous video, I discussed how a weed eater line breaks when it encounters obstacles like a chain link fence. Today, I want to address the terminology surrounding this device. I refer to it as a weed eater, while others may call it a string trimmer or weed whacker, depending on their location.
For this video, we’ll stick with the term “weed eater.” One of the most challenging decisions for me when purchasing yard products is selecting the right weed eater line. There are various options available, including different shapes and diameters of the line, which can affect cutting performance.
Today, I will use a high-speed camera to examine how different shapes of weed eater line interact with a blade of grass. Our goal is to determine which line cuts best.
In the garage, we have sectioned off pieces of weed eater line and placed them under a microscope to analyze their shapes. We will test several types: a round line, a gray round line, a triangular line, a star pattern, a dull square, and a sharp square.
After conducting tests with each line, we observed that the triangular line was quieter than the others, likely due to its design. The star line produced remarkably clean cuts, while the dull square seemed to rip through the grass rather than cut it cleanly. The sharp square line, which is heavier, also performed well but had some ripping.
We also consulted Robert, a local expert who uses weed eaters daily. He provided insights on the lines and suggested weighing them to calculate their linear density.
After analyzing the results, I concluded that for cutting thin grass, the star-shaped line is the best option due to its clean cutting ability. For thicker grass or brush, the sharp square line would be more effective because of its durability.
I hope this information helps you make an informed decision when selecting weed eater line. Thank you for watching Smarter Every Day!

This version maintains the core content while removing informal language and extraneous details.
Shape – The form or outline of an object. – In physics, understanding the shape of an object can help determine how it will move through air or water.
Line – A straight one-dimensional figure having no thickness and extending infinitely in both directions. – In geometry, a line is used to represent the shortest distance between two points.
Grass – A plant with narrow leaves growing from the base, often used in scientific studies of ecosystems. – Scientists study how grass grows in different environments to understand its role in the ecosystem.
Cuts – Divides something into parts with a sharp instrument or tool. – In physics experiments, precise cuts of materials are often necessary to ensure accurate results.
Triangular – Having three sides and three angles. – A triangular prism is a common shape studied in physics to understand light refraction.
Star – A massive, luminous sphere of plasma held together by gravity. – The Sun is a star that provides the energy necessary for life on Earth.
Square – A plane figure with four equal straight sides and four right angles. – In physics, a square is often used to calculate area and understand force distribution.
Density – The mass per unit volume of a substance. – The density of an object determines whether it will float or sink in water.
Camera – A device for capturing images, often used in scientific research to record experiments. – Scientists use a high-speed camera to capture the rapid movement of particles in an experiment.
Expert – A person with a high level of knowledge or skill in a particular area. – An expert in physics can explain complex concepts like quantum mechanics in simple terms.
