SCHOOL may still be out for sum­mer for some of you, but there are still loads of fun science ex­per­i­ments you can carry out in the com­fort of your own home!

Our friends at the Science Mu­seum in Lon­don have come up with an­other bril­liant bit of ‘kitchen science’ for you to try out. Make sure you ask a grown-up for help, though!

Milk magic!

In this colour­ful ex­per­i­ment, you will ex­plore the dif­fer­ent prop­er­ties of ma­te­ri­als and see what hap­pens when dif­fer­ent ma­te­ri­als are mixed to­gether.

Pour the milk into your tray.

Add a few drops of food colour­ing in a cir­cle near the mid­dle of the tray, so that it sits on top of the milk. You can use a pipette for this if you have one. Dip a cot­ton bud in wash­ing-up liq­uid and then dip it in the cen­tre of the milk. But care­ful not to stir, just touch the milk with the cot­ton bud. Watch the colours swirl!

Ex­tra step: Why not turn your ex­per­i­ment into a piece of art? Gen­tly lay a sheet of plain white pa­per on the sur­face and make a print of your colour­ful swirls.
