Re; Tony, et-al's - -------------------- Hi Roy, > >>> 90% of the time, when you do this, it is OK - on the odd occasion though >>> the mixture of Air to gas is just right to explode in the bunsen burner. CO2 mainly - so no explosion. All it did was make the teachers demo burner go out. Some classes connected to water!!!! ---------------------------
The water was **my** style. Problem was an accomplice - already secreted in the cupboard under trhe bench - was needed for the trick. Spend two marbles/ lend Hank Jansen/ promise a date with your sister- or the like. METHOD (To be neatly written up in chemistry 'best' book) 1. Connect a bench-water to an adjacent bench gas-tap. 2. Turn off all bunsens. 3. Sit, with attentive forward look, on the bench in front of step-1 connection. 4. Wait until Dicky-Stink (!) was ready with his demo - on the front bench. 5. 3 smart 'just swingin' your leg' heel-kicks to the under-bench door. 6. [The skilful bit - took practice] With hands behind your back, turn on the Step-1 above, water and gas taps. 7. Enjoy the enormous roof-reaching fountain that followed a spluttering front-tbench burner. 8. Do detention (again!) Note: The method never appeared on exam paper - as far as I know. Pity!
