Instructions for Speed Calculator Use:

• Set your phone or camera to film in ‘Slow Mo’ at 240 FPS (frames per second) and film an object as it travels across the grid on your Speed Square Blanket.

• Each Square is 2.19 inches and is equivalent to 1 MPH (mile per hour)

• Watch your video and count the number of squares the object travels in exactly 1 ‘Slow Mo’ second

• If your phone/camera records at 120 fps, then count the number of squares it travels in 1 ‘Slow Mo’ seconds and divide by 2. NOTE: some phones might record at 120 FPS by default but still have the ability to increase that to 240 if you check the settings.

• YOU DID IT! If your object travels 20 squares in 1 ‘Slow Mo’ Second then your item is traveling at 20 MPH!

• To calculate KPH (kilometers per hour) is easy! Just multiply your MPH by 1.6

This blanket is 40 squares wide, making it a 40 MPH blanket. If you want to measure speeds up to 80 MPH you can use two blankets and lay them end to end.
If you want to measure the speed of light, you’re going to need about 16.7 Million blankets. No big deal :)If you’ve already got plenty of blankets but still want to experiment with the science then try the following.  Measure out 2.19" squares on a piece of paper. You can fit 5 on a regular sheet of printer paper, which means you can measure up to 5 MPH. Just remember, more squares = more MPH

NOTE: This blanket is designed for objects traveling horizontally (where the speed isn’t affected by gravity). If you want to know the final speed of an egg dropped from a building right before impact for example then use this formula: Final speed = 1.25 x number of squares + 1.09

Best blanket and science tool

It's cool being able to record my own slow mo videos with my phone as well as having a nice comfy blanket when not recording. This blanket was a must buy after Mark Rober helped to inspire me to do greater things. He contributed to the confidence boost I needed to apply to NASA and eventually getting an internship! So I wanted to buy this blanket to help support the channel for him supporting me! It's made of great quality material and is perfect for a fun science pickup whenever family visits.

40mph blanket

Good day thank you for alllllllllllllllll the great and educational content. The glitter bomb for the phone scams are The prime example of doing some thing about a problem instead of sitting around and just talking about it. You help open so many people’s minds and get the every day person Learning awesome things…. The blanket is great and amazingly has multi functions witch could be the first ever multi function blanket or maybe it could be called the Swiss Army blanket :). It did take a long time to receive however due to the world shutdown and small things like that I understand. :) Cheers from Bend Oregon
