Here is a video showing how to make a thermometer just like we did on Friday.
We skipped the part where she makes a hole in the bottle lid and instead used a large amount of blu-tac to block the top of the bottle and make it airtight. Play-doh or modeling clay would work just as well.
Using a normal drink straw also meant that we didn't need the 'lolly stick' either.
Have a try at home and leave a comment to let everyone know if it worked!
