I need some help for the verification of an assignment about pendulums

[DvdP]

Hello, my name is Django and I live in the Netherlands. I've got an assignment for physics about pendulums and part of this assignment is that I need to verify my result with someone else in a country with a different gravitational force (the gravitational force were I live is 9.813 N/m²). I wanted ask you whether you'd want to help me with this.
If you want to help you should build a DIY pendulum (with some cheap and easy to find materials) and film it while you make a sling.

After this I need you to fill in this formula:

T = the period in seconds (for the swing)
l = the length of the pendulum in meters (as you can see in the picture)
g = the acceleration due to gravity in m/s2

If you would help me with this I'd be very thankful!
Cheers,
Django van der Plas

PS.
Would you please say in the video that you make it for me and Rens, so I can prove that I haven't copied it from somewhere? Thanks!

Do you attend the same school as this student? https://www.physicsforums.com/threads/calculating-gravity.947845/

Yes, thank you, I couldn't find the thread! But nevertheless, I still need someone to help me as well, since I don't think our teacher will accept the exact same results
