I made a shower head fountain that you can see in the photo below:
This is the video of my fountain working:
I used the following parts:
- shower head,
- garden hose (clear hose),
- blue tack,
- cork (at the bottom of the sculpture),
- old plastic pipe (the white pipe).
The tools that I applied were:
- electric drill (used to make the hole for the hose),
- and hack saw (used to cut the white pipe).
I did not need a hammer to insert the cork.

I made two wooden buses with two blocks of wood after seeing this article:
I used bright LEDs from a USB solar charger kit that I received from China. There were a few missing parts (rechargeable battery, wires, tools) so I decided the use the parts for another purpose.
You can see how I connected the bright LEDs (Light Emitting Diodes) from the USB charger to the yellow wires. LEDs only conduct in one direction. If the LED is not turning on then you need to reverse the polarity.
The small wooden bus has a long hole drilled in the middle that I used for the yellow wire. I could not do the same for the bigger bus because my drill was not long enough.
The wheels are made from old solar night lights metal stands/tubes. I used a hack saw to cut the metal tubes.
I also used an old Soviet double room light switch. The power supply is 3 V, that can be realised with two AA/AAA/C or D batteries connected in series. There are 3 V buttons cells but I am not sure if those small batteries have sufficient current for those bright LEDs. A typical LED needs only 2 V and can burn if higher voltages are applied.
You can my electric sculpture working in this video:
From the video you can see the 30 year old Russian switch is not perfect. It is not a good idea to connect it to mains.

I made a flying saucer from recycled components.
One part was a gear box from an old VCR (Video Cassette Recorder). Another was a shower cap. I also used 1 mm metal wire.
You can see the sculpture spinning in those YouTube videos:
Step 1: Attach the Shower Cap to Gearbox
I used pliers and thin metal wire to make a few loops in and out of the holes of the shower cap and the wheel.
Note that the small purple wheel has a bolt that is used to tighten the wheel to the gear rod.
Step 2: Put the Shower Cap Lid On
I attached the lid easily:
Step 3: Testing
I connected the gear to my bench top power supply.
This is the fastest speed that spinning sculpture reached:
The voltage from my power supply must have been about 6 V.
