I used to spend hours patiently turning the knobs of my etch a sketch a fraction at a time, scraping all the iron filings, so I could see the mechanism inside to see how it worked.

My little brother and I mostly got on well and would play harmoniously for hours, but sometimes we'd get on each other's nerves and that led to us fighting as most siblings do.

One morning my temper got the better of me and I hit him over the head with my etch a sketch (I was about 6 years old and my brother was 4). As children we are very impulsive and don't tend to think beyond the very moment we're in - but as soon as I'd done this, I instantly regretted it as it smashed open and the grey dust filled the air.

The living room soon resembled a lunar landscape - picture the TV series Space 1999 and you're pretty much in our living room in that moment.

The mess was extensive - it looked as though all the colour had been sucked out of the room which was caked in grey aluminium dust, (as was my brother's shoulder-length golden hair).

We both went eerily silent as we knew I was in big trouble - this mess was too big for us to cover up or deny, so we just sat quietly and waited for mum to wake up. Despite the mess, two small children looking very grey and sheepish, must have been a hilarious sight.

I don't remember mum being that angry afterall, the anticipation was worse - but my punishment was to share a bath with my brother, which didn't bother me too much and I had truly learnt my lesson by that point. 

For my brother's birthday this year I had an etch a sketch birthday card specially made for him. I laughed my head off as I posted it. He texted saying that he blames that moment from our childhood as the reason he's now completely bald.

My parting advice to children is to play safe and remember that your little brother will probably be taller than you one day - so be nice to him!
