My Collection Service For Loop Keeps Waiting For A Function To End?

Basically, I Made This Collection Service Text Animation And I Did A Function For The Animation, When I Play The Game I See That The Animation Plays Per Text And I Have No Idea How To Fix It :/

How To Play The Animation For All The Text All At Once?

Script:

local CollectionService = game:GetService("CollectionService")

function Rotate(taggedPart)
    local floatActive = true
    local Start, End = 0, 15
    print(taggedPart.Name)
        for i = Start, End, 0.1 do
            taggedPart.Rotation = i
            wait(.01)
        end
        wait(.50)
        for i = End, Start, -0.1 do
            taggedPart.Rotation = i
            wait(.01)
        end     
end 
for _, TaggedPart in pairs(CollectionService:GetTagged("FloatAnim")) do
    Rotate(TaggedPart)
end
