Overflowing starter

[xxkiskekyxx]

When I oxygenate my yeast starter it overflows...did I do something wrong? Its like carbonated like a can of soda.

Nope, nothing wrong, totally normal, its the CO2 pushing out, you can try using some fermcap anti foam in your starters and it will prevent that from happening but don't worry about it now, it is at high krausen and will settle down quickly. Let it ferment out, cold crash it if you can and decant when ready to pitch.
