Ula Kanduc : Amazing! I have no idea how you do all that! You have amazing animation and great cinematic techiques! Great job really!

kaye cobarrubia : Ano daw? Natanga ako dito haha. Btw ur so smart keep it up

Donna Fernandez : Kelan kya ako maiinlove sa physics? As i remember Physics is my lowest grade back in college.. hahaha! Ay pati dn pla math.. hahaha! Pano na kya kung ginawa png tagalog ang math? For example: "parisukat ugat ng ekis itaas sa kapangyarihan ng sampu" in ENGLISH. "square root of x raise to the power of 10" (Bigti na cguro tlga ako!? hahaha!)

Frank22 : *C O N G R A T U L A T I O N S* 'lupang hinirang' plays in the distance

John Campbell : Great Video!! Congrats on winning!!

lloydgeemail80 : Not all observation is right.. There is a standard referrences to that point where the observation is correct. Example: youre outside the car and im inside, which is left or right?

Axzero : Well, technically what she says at 0:13 is wrong. They're not "both right". The one who made the number, or the one who put it there, had intentions of what number it was supposed to be. if it was supposed to be both, then they're both wrong, it's then neither 6 nor 9 in that case. The case that comes closes is if the number was meant to be interpreted in both ways, but then again, what if you changed the font, where the 9 and 6 look different if swapped. The only way to find the right answer is to observe it every way possible, and the numbers history. Otherwise great video :)

Rizza Mae Salamat : Congratulations!! You make the Philippines (and the world) a better place. I hope many students and aspiring scientists will be more inspired by you! 😊 i am so proud!

Wiscompton Music : so the earth is flat, and also a globe!?!?!?!?!!?!?!?!!? every compass points to the fountain of youth.

Afif Alhauzan : How do you animate this? It is soo good and smoooth btw good video

Roberto F. : Good try, but...are you kidding me? :) The "w" traced by the light bulb it's not "the path of the light", it's "the path of your arm" while you are moving. The "w" belongs to the moving plan, the light which I want to measure the speed reaches my eyes almost perpendicularly the moving plan. The speed (or the motion) of light it's not the speed (or the motion) of a light bulb in your hand while you are moving.

Hamza Zouak : You are amazing 👏👏👏👏

Richard E. Ward : Just excellent. All the best for a wonderful future.

kimw76 : WOW! Congratulations on your win! Your video was engaging, informative and entertaining. You used graphics and sound effects like a pro! I felt like I was watching Sesame Street or the Electric Company (I’m showing my age😬). You are a very poised and articulate presenter. Your depth of knowledge is undeniable! In summary you’re awesome! Thanks for teaching this old dog some new tricks. You managed to do something that no Physics instructor has ever been able to do for me; I can comprehend physics! I look forward to your future endeavors and I hope they include educational videos like this one sooner rather than later. Your selection and use of examples indicates that you have a knack for teaching.

tubewerk : Wow! This is a really intuitive explanation - and it's very well structured and presented

manfromanila117 : congrats!!

tony p : Congratulations on your "WIN"! I bet your parents are very proud of you. Not for the prize money but because your you. Take care. Shout out from California...

Gilberto Prujansky : Empathy should be a constant.

Gio Rix : wow

Tsog Gantumur : Great video and congratulations for winning the challenge! I have a small suggestion here. Is it really true that the car is making all the pitches at the same time? This might make the impression that the car horn is a very complex thing. It seems less confusing to say that what is really happening is that the car is making something, and this something is observed in different ways, leading to different sensory experiences.

Pedro Boscardin : Congratulations! Brazil is proud of you. You appeared on TV!! Never stop disclosing science!

Andrei Narciso : WOOOH SLAAAAY!!

Aurel Marian : I feel like you make a lot of ironic jokes in real life :D people either love you or hate, there is nothing in between (or is it?)
