Build a real working hovercraft!

Build a real working hovercraft! So you want your very own hovercraft. Well once again, Reeko is here to help. Of course it's only big enough to hold a mouse (maybe two if the first one scrunches down real low) but hey, we're not old enough for a driver's license Cut a 4 inch square out of the cardboard. Punch a hole in the cardboard - you may need to get an adult to do this part. If you attempt it yourself be very careful. Make sure you punch the hole in the center of the cardboard. The hole should be the same size as the hole in the spool. Glue the spool to the cardboard on top of the hole. Make sure you glue…

Eyes in the back of your head

Build a homemade periscope Parents have eyes in the back of their heads – we all know that.  They always know what you’ve done, where you did it, and sometimes even why you did it.  We’ll never fully understand how they do this; even science cannot provide an explanation of this natural phenomena.  But, this experiment can at least put you on somewhat equal ground as we create a gadget that will literally let you see around corners… Cut off the angled top of the milk cartons so each carton has a squared off, open end. On the closed end of the carton, cut a small square hole on one of the sides.  Leave about ¼ inch of carton on each side of the hole. …

Create an oven using a pizza box

Experiment to create a real oven using a pizza box Does you family head to the kitchen table every time they hear a fire siren? Do you get even with the neighborhood bully by inviting him over to dinner? Does Dad refer to the fire detector as the “oven timer”? It sounds like your family might need cooking lessons. Well Reeko can’t (or won’t) provide cooking lessons but he sure knows how to make a cool little oven – out of a pizza box! And while we’re at it we’ll learn how thermal collectors are able to collect sunlight and convert the solar radiation into heat. The sun is an ultimate form of energy and it has produced that energy for billions of years. Solar…

Silly Putty or slime experiment (your choice)

Fine times with homemade slime (or silly putty if we tweak it up a bit) At some point you may have heard someone speak of “polymers”. A polymer is a large molecule that is made of repeating structural units. These units are connected by what is called a covalent chemical bond. A well known polymer is “plastic”. In this experiment, we will make a polymer and then add a substance that will cause the polymer chains to cross link. Cross links are bonds that link one polymer chain to another. When the polymer chains are more “bound together”, they become harder to move around and begin to gel. In a bowl, mix an equal quantity of Elmer’s glue and water. Fill a jar with a…
