Magnetic Fishing Rod and Reel

Here is the first attempt at a homemade reel for a magnetic fishing game.

the rod is a 20 inch length of 3/4" dowel. The reel is a 1/2" and 1.5" piece of 3/4" dowel and a 2" wooden wheel connected with a 1/4" dowel.

Here are the fish:

Tissue Paper Hot Air Balloon

Image
Perhaps you've seen hot air balloons for sale as science demonstrations/experiments that you fill up with hot air from a hair dryer and let float to the top of the room.  This product can be easily recreated on a smaller scale with tissue paper.  This project is a great way to demonstrate and learn about gases and density. You'll need: 5-6 sheets of tissue paper, a strip of paper, a glue stick, a marker, scissors, and  a hair dryer. The first step is to layer 5-6 sheets of tissue paper and fold them in half lengthwise. Use a marker to draw a half tear drop shape. Cut along the line and unfold the layers.  Each one will be a panel for the hot air balloon. Using a glue stick, or wet glue thinly applied with a paintbrush, glue one edge (marked in the picture above) and layer another panel on top. Pres down firmly to seal the edge. Once the glue has dried, unfold the two panels to inspect for any holes.  Make sure to seal up any gaps.

Cardboard Opaque Projector

Update: (Please scroll down for step by step instructions of original Cardboard Opaque Projector) The updated Cardboard Opaque Projector is our attempt to increase the brightness of the light chamber inside the box and therefore the projected image.     A box that is 16 x 12 x 12 inches allowed us to position the light source below the mirror and closer to the bottom of the projector and therefore closer to the image to be projected. Adding black construction paper inside the lens barrel is to help image quality by reducing glare from reflected light inside the cardboard tube. Lining the inside of the box with aluminum foil and using a light bulb reflector shade with a 7W LED light provided substantially more light as well. Due to the size of the reflector shade we had to manuever it in place behind the mirror and then screw the light socket holder onto it through the hole in the back. This is tedious but not overly so. This shows the image to be projected and the projector on it's

Thumb Piano

Materials • 1x2'' wood • small Popsicle sticks, or plastic stirrers • 3/16 x 2'' inch machine screws or carriage bolts. • wing nuts Tools  • small saw • drill and 3/16th bit • screw driver Constructing the Thumb Piano is very simple, cut the 1x2'' to length (5-8'') and then drill a hole with the correct sized bit centered and about an inch from the ends of both pieces. Use the machine screws to hold the two piece loosely together.  You can use 2 wing nuts or one regular nut and one wing nut. Insert the popsicle sticks with different lengths sticking out of the 1x2'' sandwich and tighten the nuts until the sticks don't sound buzzy when plucked. If you want to adjust the sticks you only need to loosen one nut, this is why the second wing nut isn't really necessary.  The same basic rule about tone that applied to the wind instruments applies to the Thumb Piano the longer the resonator in this case the sticks the lower
