p4 bouncer is a colour-changing glider reflector with a minimum repeat time of 24 ticks. It is a constellation containing a p4 oscillator, boat, and block. For colour-preserving glider reflectors see p4 bumper and the stable Snark reflector. It is the first bouncer able to reflect a p44 glider stream. The original form was constructed by Arie Paap in 2018.

On 8 December 2022 James Pascua posted a new variant p4 bouncer with a substantially smaller size, as shown in the infobox at right. The reduced clearance on one side means that the original p4 bouncer may be usable in some cases where the new variant does not fit.
