When combined the liquid turns into an exploding rainbow. The Red Green show makes a big thing about the handymans secret weapon - duct tape. Nick Uhas and David Dobrik stunned the internet with their successful attempt at breaking the world record for largest amount of foam produced via the elephant toothpaste experiment.
How to Create a Foam Cup Meltdown. Help them pour acetone into the bowl so it is about 12 inch deep. Make sure kids are well supervised when doing this experiment but the foam is safe to play with just not the liquid.
If you want a slimier more flexible floam you can try adding less borax. Ask your kids to put on the goggles and rubber gloves. When not in use store your floam in an air-tight container and place it in the refrigerator to prevent molding.
The sodium iodide is a catalyst.
Easy evaporation science experiments that demonstrate that a liquid can become vapour. Simply paint the water onto a flat surface and watch it evaporate.

Water evaporation experiment for kids. Its a fantastic kitchen science experiment that works for an ocean unit or a density science lesson. Try to use different amounts of water each time so that youll be able to see the different rates of evaporation. Try different surfaces different amounts of water different patterns of application etc.
If you wanted to set this up as an experiment or investigation one way to set it up is to leave the wet sand in different places sun shade indoors etc and observe how the sand in each place changes over a period of time. Use a marker to make a line at the beginning water level. These are two examples of evaporation.
5 Teacher Demonstration - Boil water in a test tube over a candle. Place plastic wrap over one of the cups. Use your eyedropper or small spoon to drop the colored water onto your paper.
The water seems to disappear but it actually moves into the air as a gas called water vapor. Demonstrate this to your children using the activities below. Each hour mark the water level and begin to look for changes.
In a similar way as water in a pot boils the level of the water falls. This week we worked on a water filtration experiment to teach the kids about water pollution and clean water. Water has lots of properties that make it just brilliant for simple science investigations.
Water can move upwards. Explain how evaporation works and where the water has gone. You can also monitor the evaporation over a longer period of time and without other people disturbing the water as you could have when observing a puddle outdoors.
