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.

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