How to keep your water in your bucket!

I was headed over to our corn & potato field to irrigate and fertilize the sweet corn. I was driving a 4-wheeler with a trailer full of 5 gallon buckets with no lids. My brother-in-law, Andy, shared a little secret with me. He said, "If you float a piece of wood in your water buckets you will find the water rarely splashes out of the bucket." I tried it and he's right!! When the waves slosh around they break on the piece of wood instead of the rim of the bucket. Thanks, Andy!!
