A floating device acting as a target for enhancing the accuracy of a urine stream. When placed inside a toilet bowl, the target provides visual stimulation and cognitive reinforcement in response to contact with urine. The target may comprise a hull with a cavity. A reactive substance may be placed in the cavity of the hull. The reactive substance may provide a visual stimulation or cognitive reinforcement when contacted by the urine stream. A top portion may be fit against the hull to retain the reactive substance in the cavity of the hull. A barrier layer may cover at least a portion of the hull and/or the top portion. The barrier layer may be semi-permeable or selectively permeable to water when contacted by a urine stream from a user.
