Two piece slip bobber

A self-uprighting bobber comprising:

• a float, the float having a float keel end, having a float visible end, and having a float bore through the float from the float visible end to the float keel end, the float bore having a float bore cross section which is centered in the float to render a combined float and float bore center line along which all net vertical forces act when the bobber is used for angling;
• a stem, the stem having a stem in-water end, a stem upper end, and a stem body, the stem body having a stem cross section just less than the float bore cross section and having a stem center line, so that the stem can be removably disposed into the float bore with the stem in-water end below the float keel end and with the stem center line coinciding with the float center line so that when the bobber is used for angling all net vertical forces act along the coincident stem centerline and float and float bore center line;
• a stem slot fully through the stem body, the stem slot having a stem slot bottom in the stem body above the stem in-water end, the stem slot having a stem slot vertical section extending from the stem slot bottom in the stem body along the stem center line toward the stem upper end, the stem slot further having a stem slot entry section which connects the stem slot vertical section with a stem slot mouth which breaches the stem body, so that a fishing line can be placed through the stem slot mouth, through the stem slot entry section, down the stem slot vertical section to the stem slot bottom;
• a stem channel, the stem channel extending radially into the stem body to just beyond the stem center line, the stem channel also extending from the stem slot bottom to the stem in-water end, so that a fishing line hook end will hang in the stem channel along the stem center line and thus also hang along the float and float bore center line so that when the bobber is used for angling all net vertical forces act along the coincident stem center line and float and float bore center line;
• and
• a stem bulge in the stem body, the stem bulge making the stem cross section just greater than the float bore cross section, so that the stem bulge can be removably wedged into the float bore with the stem slot mouth inside the float bore and with the stem slot bottom below the float keel end so that the fishing line is held loosely in the stem slot and can freely slip through the stem slot.
