How to get aphids away

It's  half June already. After a very dry May month, rain has come and everything is growing fine.
Now we are preparing for the haying. Sander is already mowing with the scythe on the lawn between the house and the barn. Also needed he to cut  all grass away under and around the electric fencing. That is now done.

Every day I work a bit in the garden, for not only our crop is growing nicely, the weeds also....
In the broad beans I discovered some aphids. They sat in the young top leafs. It's very common for broad beans to get aphids, unfortunately. To get away with them you can just pick of the top, the rest of the plant is not tasty to aphids so they will stay away then. But my plants were not that big yet, so I was looking for some other methode to get away with them. I find a methode by squirt them away with water but we don't have running water and therefore also no garden hose, how can I do this?? While thinking about it I went on with some other chars and I needed something from the barn when I spotted a high pressure spray bottle. Maybe that will do the job. I cleaned it and filled it up with water and it does the job excellent! I'm very happy now!
