How to Make a Rain Barrel/Garden watering system. This would connect to a "drip system soaker hose" not a regular soaker hose this is because it will function properly at a lower water pressure where as a regular garden hose will not. I would be more impressed to see these connected to a rain catch system rather than simply sat out by the garden - but its a good tutorial.
Moonmelon (scientifically knows as asidus). This fruit grows in some parts of Japan and is known for its vibrant blue colour. This fruit's party trick is that it can switch flavours after you eat it. Everything sour will taste sweet, everything salty will taste bitter, and it gives water a strong orange-like taste! Bucket list fruit!
