Help with hello kitty alarm clock!!?

Answer:

The radiation is short range ( and low intensity) It is a solid so doesn't leave the container and enter the air. The radiation can ionize particles by knocking an electron from the particle. The larger the particle the greater the probability that it has an electron knocked off. This causes a minute current which triggers the alarm. Pure air has no particles so does not trigger the alarm. Dust may be charged but there are so few particles of dust that the current flow would be very low. So the system is set to respond when a) the particles are big enough and b) there are enough particles. This condition is met by smoke.
It sounds like you re confusing the carving with transferring an image. You can use a solvent to transfer an image onto the rubber before you carve it, but if you re drawn your image onto the rubber, you d use a an exacto knife or a gouge to carve the image. Solvents work well to transfer images that have been created with the kind of toner used in many copiers and laser printers, but not for inkjet images. Inkjet images can be transferred onto the carving medium by reducing the color saturation, then printing on something slick like parchment paper, waxed paper, overhead projector film, etc. The ink beads on the top and is then put onto the rubber, facedown, and gently pressed. Often a solvent ink like Staz On is used to hold the image and prevent smearing caused by contact with your hands while carving.
