Ta -da it's done ooh and look at it! A lovely purple :0 ps sieve to remove bits of cabbage

Science in the garden

Cabbage juice is magical - it changes colour. if u add acid it goes red, if u add alkali it will turn blue or green or even yellow

we tested

lemon juice

vinegar

tonic water

salt

toothpaste

soap

bleach

oven cleaner

to see how acidic-y or alkali-y they were

the results:

Acid test

I wasn't very surprised that lemon juice and vinegar went red (the best colour EVER!!!!!!) - they are both acids

But this 1 was a surprise INTRODUCING FIZZY DRINK..........................................................................................................IT WAS AN ACID!

Fizzy drinks are acid!

FIZZY DRIKS CONTAIN CARBON DIOXIDE, THAT'S THE BUBBLES. THIS GAS REACTS WITH THE WATER TO MAKE AN ACID. SO FIZZY DRINKS ARE ACIDIC.

NEXT UP IS SALTY TOOTHPASTE.....(SOWWY SALT & TOOTHPASTE) :)

Salt & Toothpaste - alkiline or acidic?

THE COLOUR DIDN'T CHANGE, THEY ARE BOTH NEUTRAL - NEITHER ACID OR ALKALI

NOW, FOR ALL THE BAKERS OUT THERE, BICARBONATE OF SODA...........................

Bicarbonate of soda - a little alkiline

IT WENT BLUE!!!!! SO IT'S AN ALKALI

NEXT UP SOAP!!!!!!

Soap - more alkiline

SOAP IS AN ALKALI. WHEN ADDED TO CABBAGE JUICE, IT TURNED IT BLUER THAN BICARBONATE OF SODA, SO IT'S A STRONGER ALKALI.

NEXT UP BLEACH :( STINKY BLEACH

Bleach - Even more alkiline

IT WENT GREEN!!! MEANING BLEACH IS A STRONGER ALKALI THAN SOAP!

TIP: DON'T ADD TOO MUCH BLEACH OTHERWISE IT WILL DRAIN OUT THE COLOUR! IT IS CALLED BLEACH FOR A REASON PEEPS!

NOW TIME FOR ALKALI OF THE DAY.....OVEN CLEANER

Oven cleaner - super alkiline

IT WENT BLUE THEN GREEN THEN A GREENY YELLOW - THIS IS A VERY VERY VERY VERY STRONG ALKALI!!!!!!!

IT'S THE STRONGEST AKALI OF THE DAY - YAY, GO OVEN CLEANER!!!!!

THIS EXPERIMENT IS REALLY FUN!! TRY IT AT HOME!!! (JUST GET AN ADULT TO HELP YOU WITH THINGS LIKE BLEACH OR OVEN CLEANER)
