STEAM - LIGHTS, SOUND, ACTION!


 Last time in 

STEAM

  LIGHTS, SOUND, ACTION! 

Hover Plate

Using two Styrofoam plates, rub the backside of one with a cotton cloth and see how they repel each other.


Can Can Go
Rub pipe with cloth, lay the can on its side.  Hold the pipe lengthwise (horizontal) to the can without touching it.  You can drag it and pull it from side to side using “THE FORCE” or static.

  Stick around

Using a stick about 2 inches long, tie thread around it and allow to hang from the middle.  Tape one end of the thread to the inside bottom of the jar, leaving enough thread with stick, to dangle when turned over.  Rub pvc with cloth.  Touching the jar, move pvc pipe on outside of the jar side to side and watch the stick move away from pipe and toward the pipe.  It appears to “stick” to the side of the jar.



Bubble Trouble (tricky to make bubbles)
Pour small amount of bubble solution onto sheet of plastic and spread out using the wand.  Using the straw, blow 1 bubble onto the surface so it sticks.  Use pvc pipe to pull and drag across sheet without touching the bubble. Now make 2 bubbles on the surface.  Using the pvc pipe, try to divide the bubbles from each other by placing the pipe between them without touching them.


Dancing Balls 
Cover styrofoam in tinfoil and make a ball. Wipe polycarbonate sheet with cotton cloth.  Drop a “ball” on top of the sheet; use your finger without touching it, to move around polycarbonate sheet.  What happens? 
Add more balls under the sheet into the tray and place sheet back on top. Wipe surface. The balls will “stick” to bottom of the lid of sheet as you move your finger over the sheet.


 
Balloon Tight 
Blow up balloons, knot, and tie thread to ends.  Rub pvc with cloth and try to gently move balloons without touching the balloons


Electroscope
Pull wire through the cork lid then bend wire into spiral at one end. Push wire into a small piece of straw and spiral part to hold it in place.  Push wire and straw into cork lid.  At other end of wire, bend it into a hook.  Take 2 small rectangles of foil and punch holes at one end and drop it onto the hook.  Wipe pipe with cloth.  Move pipe around jar and watch foil “dance”.

Wingardium Leviosa 
Using plastic shopping bags, cut large circles from them.  Wipe pipe with cloth.  Rub the circle bag on your shirt.  Now toss bag-circle into the air and use the pipe to keep it suspended in air without touching it.

DIY vibration salt Chladni,

  Using a speaker and music. 
Pick a song with a lot of bass and have volume turned up.  Place the sheet of paper on top of the speaker.  Pour salt or sugar onto the paper and watch it dance to the beat.

This video is pretty good as a demonstration: https://www.youtube.com/watch?v=9uEeADQN8Jo
