After 4 years away from SD, I'm building a new starter!

I put 1/4 c water and 1/2 c whole wheat flour into a jar yesterday
morning, discarded half after 24 hours then added another 1/4 c water
and 1/2 c whole wheat flour. After only a couple of hours it started to
bubble, and now (only 8 hours after the last feeding) it has tripled in
volume, and threatens to grow out the top of my jar. (This is the
fastest and most energetic starter I've ever made! This is exciting!)

Normally, I would feed it again tomorrow morning, but I'm afraid it will
overwhelm the jar if I let it continue.

Should I stir it to knock it down and let it continue, unfed, til to
tomorrow morning's scheduled 24 hour feeding? Or should I transfer it
to another jar and follow through with the 24 hour feeding cycle
tomorrow morning? Or do you think is it ready to be used in a loaf?

Thanks,

Java
