[To all users]

• Portable because all the contents needed for electrostatic field observation can be put in a storage/carrying wooden box.
• Both the dielectric substance powder and silicon oil are safe materials contained in the sealed observation cell, while conventional way of demonstrations to observe electrostatic field requires some chemicals such as tetra chlorocarbon.
• Demonstration is repeatable because of the sealed observation cell.
• In stead of the piezoelectric device comes with the product, Narika’s Static Genecon (B10-1324-W0) can be used as a power supply.

[To teachers]

• Possible to safely and repeatedly demonstrate how lines of electrostatic force are generated and change depending on the pattern of electrode plates.
• Easy to agitate the dielectric substance scenery powder (in the silicon oil) in the observation tank by shaking it with hand and smoothly move onto next observation after changing the electrode plate.
• It is recommendable to use digital camera to project the phenomenon of the electrostatic field and share it with students in a science classroom.
• Easy to prepare because of the sealed observation cell included dielectric material powder.

[To students]

• Easy to compare the lines of electrostatic force generated by changing the electrode plate.
