@jschwart that also works! though just in case: the hole does not have to be perfectly round, those little taps you can get at the hardware store have large silicone seals that will cover up any uneven parts. if the bucket drops sometimes it may be worth mounting the tap on the side near the bottom instead of on the bottom, then at least it shouldn't take a direct hit when it does drop down. they're pretty cheap (~2-8$ over here), could be a fun experiment perhaps c:
