I had a BSA Meteor too, the super version that had the rubber end to the shoulder stock. Cracking rifle, especially with an Airsporter spring

I can confirm that you get a loud pop followed by funny burning smell and a few blobs of red plastic on the bench when you connect a single red LED across about 20 (whatever I found in battery cupboard in the physics lab) PP9 batteries wired in series.
Connecting a car headlamp bulb to the mains is not a good idea. You do get nice bright light which you will still see whenever you blink for the rest of the day but bulb life is rather short....
It wasn't me but someone thought it would be fun to leave the chuck key in the lathe in the metalwork room and start it up. The caretaker was most unhappy about having to replace a window frame...
Turning of the fuel cut off valve on the bus belonging to a visiting hockey team was good fun when the bus airlocked going out the school gates, blocking the onl;y entrance and the headmaster couldn't get his car out to go home![]()
well, you'd not have had 3amps through your body - a few mA tops (even though the supply would give 3A into a short circuit or a motor), and 240v 100mA will quite likely kill you.
Remember V= IR (volts, current, reistance). Thus 240v will give 20x the current if the resistance is the same. 12v will never drive 3Amps through your body, whilsy 240v will give 20x the current. (subject to not exceeding the capacity of the power supply - in which case won't be full stated voltage)
I recall a colleague removing the limiting resistor from a neon mains indicator and then deciding to check that it still worked by connecting it across the mains. A loud bang followed by a new purchase.
My Dad had a mechano steam engine as a boy. I think you filled the burner with Meths. It actually didn't seem too dangerous when he showed me it when i was about 12. And unlike modern toys, it still worked after 50 years of sitting in the loft

I never got Mamods.Yes, my dad had one too. He always had a damp cloth on hand in case the thing set on fire

We've not seen @vernon on here today. I hope he didn't blow himself up in his shed yesterday![]()

I bought a similar sort of thing from a former RR worker who retired to St Ives. Great fun. You can get solid fuel for them or use barbecue lighter blocks
Back in my school days we used to put carbide in the inkwells.Good God!!! That Gilbert chap was probably responsible for a lot of serious injuries or even deaths.
Wasn't Calcium Carbide used in old bike lamps (when my Grandad were a lad).
Giving kids are formula for Black Powder and saying they could only make it in the small amount. I'm sure they would do that.
