How to make player no gravity?

How to make player no gravity.

Like when you catch the Balloon on Super Mario World.

I maked script like this.

local part = script.Parent
local head = 0.1

part.Touched:connect(function(hit)
    local player = game.Players:GetPlayerFromCharacter(hit.Parent)
    if player then
        script.Disabled = true
        script.Sound:Play()
        player.Character.Humanoid.HeadScale.Value = 1.1
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.2
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.3
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.4
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.5
        player.Character.Humanoid.Gravity = -2
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.6
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.7
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.8
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.9
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 2
        wait(15)
        player.Character.Humanoid.HeadScale.Value = 1.9
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.8
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.7
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.6
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.5
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.4
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.3
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.2
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1.1
        wait(head)
        player.Character.Humanoid.HeadScale.Value = 1
        player.Cahracter.Humanoid.Gravity = 0
        script.Disabled = false
    end
end)
