Paper Spray Ionization

Video S1: Gas evolution during plasma exposure

Video S2. Ground above hydrophobic triangle

Video S3. High speed droplet vibrations observed

Video S4. Droplet vibrates and then jumps

Ground on side of hydrophobic triangle

Video S5. Solvent 2 (Surface tension 62 mN/m). When voltage is applied, the solvent vibrates

Video S6. Solvent 4 (Surface tension 41 mN/m). When voltage is applied, the solvent vibrates more vigorously

Video S7. Solvent 5 (Surface tension 38 mN/m). When voltage is applied, the solvent vibrates, momentary taylor cones are observed

Video S8. Solvent 7 (Surface tension 29 mN/m). When voltage is applied, the solvent forms multiple taylor cones from the paper fibers protruding from the flat edge of the paper strip
