I do this one at work all the time. The children suggested adding colour to the vinegar (I used food colouring) and placing the canister onto paper. I makes a great "Fireworks painting"Lorina wrote:I was at work and I did this experiment with the preschoolers... they loved it!
You need to have these: A small film canister ( you can often pick these up for free!), Vinegar, Bicarbonate Soda, Mixing bowl and spoon, Water and safety goggles.
Here are the Instructions:
1. Take one teaspoon of bicarbonate soda and place it into the dish.Add 5 drops of water and mix into a thick past.
2. Use the spoon to pack the bicarbonate soda paste onto the underside of the film canister lid. Often the clear styled film canister's work better, as you can place the bicarbonate paste into the small well that exists. The other bonus is that the lid tends to be tighter, thereby the rocket flies higher! Why is this so?
3. Fill your film canister halfway with vinegar. You're ready for launch!
4. Gently clip the lid onto the canister, making sure that the whole lid is secure.
5. Making sure your safety goggles are over your eyes, turn the entire film canister upside down onto it's lid on a flat surface. Stand back and watch it fly!
Hope you enjoy!

That's a really good idea! I guess it can get really messy so it probably needs to be outside. I'm going to have to try your suggestion by adding food colouring to the vinegar next time!pabby1979 wrote:QR_BBPOST I do this one at work all the time.
