Bicarbonate rockets in slow motion

Lockdown chemistry
Fun chemistry experiments you might choose to do at home.
Safety first
Do not stand over, put your face close to or point a bicarbonate rocket at anyone during launch. Stand well back and enjoy.
DO NOT USE GLASS BOTTLES
Requirements
A small plastic bottle
A bung (cut from a rubber pencil eraser to fit the mouth of the plastic bottle)
10ml vinegar, approx.
0.5g of sodium hydrogen carbonate, approx.
Half a square of soft toilet tissue
Procedure
Pour the vinegar into the bottle to a depth of 0.5 to 1 cm
Spread the sodium hydrogen carbonate onto the tissue paper and fold the edges of the paper forming a cylinder with the sodium hydrogen carbonate inside
Fold the tissue paper into a U shape and twist the two ends light together
Holding the bottle almost horizontal, insert the tissue paper until the end just protrudes from the mouth of the bottle
DON'T LET THE PAPER COME IN CONTACT WITH THE VINEGAR AT THIS STAGE
Insert the rubber bung, trapping the end of the paper
Place the bottle vertically on a flat surface, standing on the bung and stand back for lift-off
Enjoy and repeat as necessary
The chemistry of the chemical reaction between ethanoic acid and sodium hydrogen carbonate can be explored
acid + carbonate = salt + carbon dioxide + water
Have fun with small scale chemistry and microscale chemistry
