Preparing a bicarb rocket at home PXL 20210815

Lockdown Chemistry School Experiments
Chemistry experiments you might be able to do at home under lockdown.
SAFETY FIRST - GET AN ADULT TO CUT THE RUBBER BUNG OUT OF A SOFT PENCIL ERASER USING A SHARP KNIFE.
Part 1 Making the rocket
In this movie clip you can see an example of materials you might be able to obtain from the supermarket in order to make a small bicarbonate rocket.
The small plastic bottle used was approximately 20 - 30ml capacity and was an inexpensive candy container.
The remaining equipment is probably familiar and should be low cost.
Materials list
Small plastic bottle
Soft rubber pencil eraser
White vinegar -although any vinegar found in the kitchen should work
Bicarbonate of soda - sodium hydrogen carbonate
A sheet of tissue paper
Sharp knife to cut out the rubber bung - make sure an adult does this
When the rubber bung is cut out from the eraser its best to cut out a cone shape to ensure an airtight fit in the bottle when the bung is inserted. See next movie clip.
Have fun with chemistry experiments at home when you can, even under lockdown.
Thanks to Jonathan Barton, Bob Worley and Abdul Khan for inspiration and encouragement.
