Great Performance

Yesterday we went and saw “Brainiac Alive” at QPAC.

It was a little Science mixed with a lot of loud entertainment

(and I DO mean LOUD!)

It was excellent and we thoroughly enjoyed it!

So, if you are looking for something to do these school holidays,

definitely grab tickets to Brainiac Alive,

although you’d better be fast as their last performance is on the 13th January

and I bet tickets are selling like hot cakes.

Yes, we were in this audience.

Thinking of Getting a Tattoo…Don’t

We stumbled on these Science videos about tattoos and were horrified.

I did not know that they stab you with multiple needles.

I also didn’t know that the tattoo ink contains toxic heavy metals, especially the coloured inks.

Nor did I know that your body treats the ink left under your skin as a poison and attacks it (it makes sense though).

We found the tattoo removal process the most interesting.  It’s actually your body that removes the tattoo.  The laser just breaks down the ink into smaller particles that your body can deal with itself.

No, there are no tattoo lovers in this house.  We think they are hideous and can’t understand the thinking behind why people would want one…especially after watching these videos!

I wonder what the research will say about the dangers that tattoos pose to our health once they gather enough data about it.  Tattooing has only really become a popular mainstream activity in the last generation or so.

Cigarettes were first manufactured in the second half of the 1800s and major research linking them to death didn’t become widely known until about the 1950s.  So perhaps a hundred years of people dying before they figured out the link.

How long will it take for tattoo research?  There’s already murmurings about the dangers.

An Electronics Kit

This term, we’ve been working through an electronics kit from Jaycar.com.au.

001 (Small)

It’s a brilliant starters kit as it comes with all of the components you need.

(You can actually buy the book by itself if you choose.

None of the other books in this series comes in a kit format, which is a real shame).

007 (Small)

The projects start out very simply, creating a circuit to light an LED bulb

011 (Small)

and proceed to much more complex projects,

teaching you about the components and how your circuits work as you progress.

006 (Small)

This project was Brayden’s “Heads or Tails” machine.

When he used his ‘probe wire’ to complete a specific circuit, it lit up both LED bulbs.

What you can’t see, because it’s happening so quickly, is that the lights are flashing alternatively.

014 (Small)

When you break that circuit and allow a different circuit to flow, one of the two lights will remain on.

It seems ‘random’ because you have no idea which light was ‘on’ at the time that you broke the circuit,

thus creating a random-like machine for occasions when you need a ‘heads-or-tails’ answer.

Clever, huh?  We thought so.

013 (Small)

Our only complaint with this kit is that the springs that replace the need for soldering,

are actually quite difficult (and painful) to use.

So, wiring up these circuits takes a bit of time and is quite fiddly.

I suppose the good thing about it is that it makes the user very keen to move onto the next kit that does require soldering.

A Little House Guest

This little fellow flew into our home today.

Isn’t he absolutely exquisite?!

Of course, he could be a she.

How does one tell the difference?

Regardless, we just loved this little critter.

After a bit of googling, we discovered that he’s most likely a cuckoo wasp.

(Here’s some info about him if you are interested).

009a (Small)

The species is a bit of a bully in the insect world.

They lay their eggs in the nests of other insects

so their larvae can feed on the resident larvae.

They usually target hornet nests,

and we aren’t fans of hornets, so we are definitely on Team Cuckoo!

We gave him a little piece of apricot while we took some photos

(which was pretty generous as those apricots cost us $12.90 a kilo!!).

063a (Small)

We could have gazed at his iridescent colouring all day long,

but, we eventually released our little visitor to the outside world.

It just amazes me that even the tiniest creatures are created with such attention to detail.

His little visit reminded us that we need to notice beauty in our world,

even when it’s found in such tiny forms.

🙂
