Lots of people ask me about science parties and the best experiments to keep children entertained at a science party. Science Sparks is full of fun, safe and hands-on science activities, but here are some I think would work best at a kid’s birthday party.
Lava lamps are super simple to make, and the perfect take home gift as they are completely reusable with the addition of a bit more alka seltzer. You could make a beautiful display of different coloured lava lamps and use as party favours at the end, or even give the kids a ‘make your own lava lamp kit’ in a little bag.
The infamous coke and mento trick
Drop a couple of mentos into a bottle of coke and stand back! Does it work with diet drinks? Or different sweets?
This activity is simple, easy to explain and very hands on. Just add some coloured water to a plate or bowl and have some different materials on hand to see if they stop the sugar cubes absorbing the water.
Make a LEGO house and test different roof materials
Sticking with the absorbing theme, you could make lots of little LEGO houses and provide sticks, leaves etc for the children to use as the roof and then spray with water to test how watertight they are.
Impress the kids and grown-ups with these simple science magic tricks.
