Cracking the Code: What the Black Dots on Your Car’s Windshield Mean Black dots on car windshields are important but frequently ignored, according to experts.The frit band, a textured enamel paint strip that encircles the windshield, is made up of these dots.
By using this band, the windshield is “ensured to be securely attached to the vehicle.”By preventing sunlight from gradually degrading the adhesive connection, the black dots shield the adhesive from damaging UV rays.
During manufacturing, the tiny dots that make up the dot matrix provide uniform temperature dispersion throughout the windshield.This procedure guarantees that straight lines on the glass stay true and prevents optical distortion, sometimes known as “lensing.”The transition from transparent glass to the black frit border is aesthetically attractive because of the black dot matrix’s slow fading.
This design lessens the possibility of damage while strengthening the windshield’s structural integrity.In essence, the seemingly small black dots on your windshield have several purposes and are crucial to the intricate architecture of your vehicle.

Challenge: Can you solve this math problem for middle schoolers – without a calculator?
Classic brain training methods are perhaps puzzles like crosswords or sudoku, but I have recently become more attracted to the type of challenge you’ll see below.
These puzzles have been flooding the web lately, probably because they are really fun!
These are old classic mathematical problems. When you were in middle or high school.
These math problems are more fun when you find yourself trying to remember the math you learned as a child.
Can you figure out the correct solution?
Here is the challenge, in the picture below.
At the top of the picture, we see the task and then four possible answers.
Which solution do you think is the correct one?
How did you come up with it?
Take your time and think about it to find the correct solution.
Done? Below you can check if you picked the right number!
A
B
C
The correct answer
The correct answer is B: 12.
Why is 12 the correct answer?
Well, if you remember from your school days, according to the order of operations, you do multiplication before addition and subtraction, so you start by solving 3 x 3, which results in 9.
Then we are left with a simpler math problem: 3 + 9 – 3 + 3
The answer is therefore 12.
Did you pick the correct number? Congratulations!
