Rocket Power!

This afternoon we went out to see the rocket that Mr McMillan and Room 11 had assembled for science week.
Mr McMillan and I filled the bottle with vinegar and the firing tube with baking soda as it was a bit tricky to line it up.
We waited for it to blast off!

Oh dear! 
Nothing happened! 
We refilled it and tried again. Success! 
It took off so fast we missed getting a photo of it taking off into the air!
Everyone cheered!
Thank you Mr McMillan and Room 11!
