Wonderful, educational video. My middle school class studying physics and leverage were toally into this! We are going to try it out! Thank you.

I am totally doing my well like this, it seems like the absolute cheapest way to do it. I just wonder why have a separate drill bit and bailer? It seems to me by having a 10 cm blade or teeth below the bailer flap/valve, you can also use the bailer to cut through most material, or am I missing something? The flap just has to be robust enough not to get damaged by all the pummelling. It would save a whole bunch of time so you don't have to keep pulling the tool out and swapping them, especially once you are many metres down, it's a huge job just pulling the bit up to the surface every time, swapping it out for the bailer and putting the bailer back down..?

If you are drilling through soft formations, like sand or mud, you may be able to do so with just a bailer. However, if you have to drill through harder soils, with rocks and consolidated layers, the bit will chop things up so they fit into the bailer. The whole process is about making mud and lifting it to the surface. If the soils you're drilling through turn readily into mud, you're golden!

@@cliffmissen5369 Gotcha, thanks, yeah, we've got pretty much nothing but clay for 100 m down, so I am forgetting people have rocks and all sorts to get through. I think I am going to start out with just the bailer and see how far we get. I'm not really expecting to get through 100 m that way, but I CAN be very persistent, so we shall see :)

11,000 BC when hard steel was made by chinese that wud crush rock. deepest cable tool well 11,125 feet in NY STATE, USA. natural gas well. that must have taken FOR EVER!!! rotary rigs now can do it in 10 days with modern drag PDC bits... and big drilling rigs with HD motors.
