No, these aren't tears in our eyes, it's just...our spider-sense goin' crazy. Yeah, that's it.

 

From the Youtube description:

I had a replica Spider-Man suit made so i could surprise my son on his 5th Birthday. Unfortunately he has been diagnosed with a Grade 4 Brain Stem Tumor with an average of 1 yr to live. I'm so proud i managed to do this for him, and secretly filmed the surprise with my Go Pro 3+ :)
