I don't think this is possible, at least with the version of cron in
potato.

Nope. That entry will run every 10 minutes. I don't think the crontab
format allows you to specify seconds. See crontab's manual page (in section
5) for details.
If you're not terribly concerned about the exactness of the timing, the
following should work nicely:
#!/bin/sh
while /bin/true
do
/bin/ping -s 8 -c 1 www.sunet.se 1> /dev/null 2>&1
/bin/sleep 10
done
