Science is fun!

In case you didn't know it...science is so much fun!  Dr Ferrar came to Room 10 on Friday and surprised us all with an amazing 'show'.  There were balloons, hydrogen gas, explosions and fire!  It was spectacular!

Dr Ferrar lit a wick and when he put it up to the balloon...BOOM!  We had to stand well back and block our ears very carefully.  No Room 10 work was harmed in the making of this explosion :-)

Some of the things Room 10 said afterwards were:

• Hydrogen explodes when fire comes near it
• Scientists wear a special coat to protect their clothes when they do experiments
• The explosion was so loud!
• There was so much fire!
• Can we do that again...??!!

We learnt that hydrogen and helium both make balloons float up but that helium is expensive so it is better to use hydrogen.  We wonder if hydrogen makes a better explosion too?  It really made us ecstatic!
