Biomes

Slight but very fun deviatiaion into other subjects.

I made a Pond Biome and a Moss Biome.
Both are sealed units so we'll see how they go :-)

Pond Bio is slowly clearing and it turns out I have a baby SWAN MUSSELL in there !
Also some Daphnia and other unknown wibbly gribbly things.

The Moss Bio has a few diff species of Moss and some landscaping that I couldnt resisist.

I also made a couple of Micro Moss Biomes, with a tiny amount of sand and substrate and a tiny amount of Star Moss.  I also added some micro lanscaping to those and they look ace :-)

Resonance Tubes

These are for measureing sound resonance at different lengths.
Cutting perspex tube is a pain in the a.....

Slippery Slope

Got a ramp built.
Will be using this for friction tests, car crash and acceleration experiments, and a host of other things.

Wizzy Mixer

Another Wizzy Mixer failing.
Same as last time, stripped it, cleaned it, lubed it.
Readjusted the bearing sleeves.

Wizzy Mixing again !

Hovercraft

Building some model Hovercraft....

Some basic materials...

Make sure to let them dry well....

Blow up a balloon, add it to the drinks nozzle, and the air deflates underneath creating a cushion of air the CD can ride on..... 

UPDATE

The No more Nails failed !

Cant believe it, they all just fell off.

Now trying Superglue, and Strong PVA.

We'll see what works.....

Electroscope

Lesson learnt. Working with Gold Leaf is a total  #@!  of a job...

Needed to fix two Electroscopes.
There's a tiny piece of gold leaf about 2 atoms thick, glued at one end to a metal probe.
I had to cut new leaf and stick it to the probe. Its a nightmare to cut as it just tears.

Much swearing later, I got it done :-)

Blue & Green stuff.. makes Brown stuff

Been looking into learning a little basic chemistry.
Interesting stuff.
And loving my Junior Chemistry book.  :-)
