Speeeeed !

Measuring velocity and potential energy.

 

Biome

The Pond Biome has finally settled properly.  The particulates in there must have been VERY fine as they took  along while to settle.
Lots of wiggly gribbly things in there and the weed seems to have perked up. :-)
Hoping the balance of Oxygen and Carbon dioxide works out well.

Moss Biome appears to be settling in.  I'm sure its looking better than it did at set up.

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.  :-)

Wizzy Mixer

This thing heats and mixes liquids / chemicals by whizzing a metal bar around via Magnets underneath.
Its whizzer was stuck.
I fixed it.

Melting point kit

Fixed.

This thingy had glass and corrosion stuck in some VERY tiny tubes in a brass heating block.
Works a treat now :-)

Tested it afterwards and the heat got to 240oC.

Obviously I burnt myself on it. :-(
Here's a FLIR image to see the heat. It also shows the heat travelling up the thermometer.

Solar System Poster

How utterly amazing is this poster?

Earth-like Sytem

The Trappist System.

Couple of earthy types there!
Could life already be there?

Alchemy

Love this lol

Instead of using Lead, I might try and turn morons into gold.
I wouldnt be short of materials.....

Hydroponics

Slowly getting there...

Steam

Had to build a steam generator for a demo...

Indiana Jones

To paraphrase Indy...

"Maths, why did it have to be maths....."
