Science experiments with plastic bottles (discovery bottle, lava lamp, magnet bottle, blowing up a balloon and plastic bottle links)

This summer we having been enjoying lots of science play in our garden. Here our some of our recent science experiments with plastic bottles.

DISCOVERY BOTTLE

We made a discovery bottle using a large plastic bottle, water, vegetable oil, glitter and sequins.










Later we added coloured glass stones (which make a nice sound when the bottle is shaken),



and some red food colouring.



MINI LAVA LAMP

We used a small plastic bottle to make a simple mini lava lamp. We filled the bottle three quarters full with vegetable oil and then filled the rest with a mixture of water and blue food colouring. This works best giving the bottle a good shake.









PIPE CLEANER MAGNET BOTTLE

We cut pipe cleaners into small pieces and put them in a plastic bottle, then used a magnet to move them about inside the bottle.



BLOWING UP A BALLOON

We used a plastic bottle, vinegar and bicarbonate of soda to blow up a balloon. This was inspired by Little Homeschool Blessings who posted instructions at Balloon Experiments and linked up at the Summer Carnival. I knew Sunnyboy would love this experiment!
