These experiments are from Robert Krampf - The Happy Scientist
241 - Brain Freeze - The reason thirty percent of people get brain freeze from eating ice cream. Body warmth and why it leaves your feet and hands first.
242 - The Five Cents - Your sense of hearing. Every day you hear all sorts of sounds that you really don't pay attention to.
243 - Water Magnifier - How can a drop of water make things look bigger? As light enters the drop of water, it slows down. If the surface of the water is curved, the light is also bent into a new path. The rounded shape of the drop bends the light outwards. As the light spreads out, the image that you see gets larger.
244 - Ice Race - Freezing water in different size containers. Why does the surface area make a difference?
245 - Rolling Bottles - This week's experiment is a fun one and may be surprising. Fill a bottle with dirt and a bottle with water. Which one rolls farther?
246 - Paper Worms - How does a wrinkle releaser work?
247 - Saving Water - Even little things, such as stopping a drip or turning the water off while brushing teeth, can make a big difference in conserving water.
248 - Relative Speed - We are going to see that how fast things seem to be traveling can vary quite a bit, depending on where you are standing.
249 - Milk Bubbles - Why can you blow bubbles easily in milk, but not in water?
250 - Water, Oil and Ice, Oh My - This week, we are going to explore the world of density. This is a very useful science, important for many things from boats to hot air balloons.
