It's totally a fake. Hydrogen peroxide IS an ingredient in luminous
binary reactions. So the people probaby dumped the Mountain Dew and
replaced the 1/4th bottle amount with glow-stick contents.
The people clearly just emptied a stick or two worth of "stick-fluid"
into a mountain dew bottle. The stick-fluid is phenyl oxalate ester
and some dye (green in the videos).
The fluid in the tiny vial (inside the light sticks, the thing that
breaks when you bend or snap them) is just hydrogen peroxide. So the
guys just added that with the baking soda.
In fact, they COULD have left SOME of the Mountain Dew in there
because with the baking soda, you get added carbon-dioxide production,
which might generate additional peroxyacid breakdown reactions (might
slow it down too... hard to say without working it out on paper).
Either way, the Mountain Dew + H2O2 (peroxid) and NaHCO2 (baking soda)
won't have ANY luminescent reaction at all.
